As mentioned in https://github.com/certbot/certbot/pull/7712#discussion_r370419867, it's time to remove this ciphersuite now that Windows 2008 R2 and Windows 7 are EOLed.
* Remove ECDHE-RSA-AES128-SHA from NGINX ciphers list to celebrate Windows 2008 R2 deprecation
* Update changelog
Part of #7550
This PR makes appropriate corrections to run pylint on Python 3.
Why not keeping the dependencies unchanged and just run pylint on Python 3?
Because the old version of pylint breaks horribly on Python 3 because of unsupported version of astroid.
Why updating pylint + astroid to the latest version ?
Because this version only fixes some internal errors occuring during the lint of Certbot code, and is also ready to run gracefully on Python 3.8.
Why upgrading mypy ?
Because the old version does not support the new version of astroid required to run pylint correctly.
Why not upgrading mypy to its latest version ?
Because this latest version includes a new typshed version, that adds a lot of new type definitions, and brings dozens of new errors on the Certbot codebase. I would like to fix that in a future PR.
That said so, the work has been to find the correct set of new dependency versions, then configure pylint for sane configuration errors in our situation, disable irrelevant lintings errors, then fixing (or ignoring for good reason) the remaining mypy errors.
I also made PyLint and MyPy checks run correctly on Windows.

Summary of changes in this PR:
- Refactor files involved in the `certbot` module to be of a similar structure to every other package; that is, inside a directory inside the main repo root (see below).
- Make repo root README symlink to `certbot` README.
- Pull tests outside of the distributed module.
- Make `certbot/tests` not be a module so that `certbot` isn't added to Python's path for module discovery.
- Remove `--pyargs` from test calls, and make sure to call tests from repo root since without `--pyargs`, `pytest` takes directory names rather than package names as arguments.
- Replace mentions of `.` with `certbot` when referring to packages to install, usually editably.
- Clean up some unused code around executing tests in a different directory.
- Create public shim around main and make that the entry point.

On Windows you can have several drives (`C:`, `D:`, ...), that is the roughly (really roughly) equivalent of mount points, since each drive is usually associated to a specific physical partition.
So you can have paths like `C:\one\path`, `D:\another\path`.
In parallel, `os.path.relpath(path, start='.')` calculates the relative path between the given `path` and a `start` path (current directory if not provided). In recent versions of Python, `os.path.relpath` will fail if `path` and `start` are not on the same drive, because a relative path between two paths like `C:\one\path`, `D:\another\path` is not possible.
In saw unit tests failing because of this in two locations. This occurs when the certbot codebase that is tested is on a given drive (like `D:`) while the default temporary directory used by `tempfile` is on another drive (most of the time located in `C:` drive).
This PR fixes that.
Following discussions in #7298.

This PR is the second part of #6497 to ease the integration, following the new plan propose by @bmw here: #6497 (comment)
This PR creates the module certbot.compat.os, that delegates everything to os, and that will be the safeguard against problematic methods of the standard module. On top of that, a quality check wrapper is called in the lint tox environment. This wrapper calls pylint and ensures that standard os module is no used directly in the certbot codebase.
Finally local oldest requirements are updated to ensure that tests will take the new logic when running.

This PR is a part of the tls-sni-01 removal plan described in #6849.
This PR removes --tls-sni-01-port, --tls-sni-01-address and tls-sni-01/tls-sni options from --preferred-challenges. They are replace by deprecation warning, indicating that these options will be removed soon.
This deprecation, instead of complete removal, is done to avoid certbot instances to hard fail if some automated scripts still use these flags for some users.
Once this PR lands, we can remove completely theses flags in one or two release.
* Remove tls-sni related flags in cli. Add a deprecation warning instead.
* Adapt tests to cli and renewal towards tls-sni flags deprecation
* Add https_port option. Make tls_sni_01_port show a deprecation warning, but silently modify https_port if set
* Migrate last items
* Fix lint
* Update certbot/cli.py

This PR is a part of the tls-sni-01 removal plan described in #6849.
This PR removes the tls-sni-01 challenge tests during the integration tests. The approach I used here is not to remove completely the existing test code, but simply editing it to use a http-01 challenge. Indeed:
* the current integration tests are strongly coupled, and would require more modifications that it is worth, because ...
* the certbot-ci project, that has already no tls-sni tests, will soon replace completely the current integration tests code.
If you execute `tests/lock_test.py` or `tox -e integration` on a fairly recent machine, you will get the following error during tests executing against a live Nginx instance:
```
no "ssl_certificate" is defined in server listening on SSL port while SSL handshaking, client: x.x.x.x, server: y:y:y:y:z
```
Indeed, having no defined ssl certificate for a ssl port would inevitably lead to an error during the handshake SSL process between a client and this mis-configured nginx instance.
However it was not a problem one year before, because the handshake was not occurring in practice: the test just need to have a nginx started, and then immediately proceed to modify the configuration with a correct SSL setup. And nginx was able to start with a mis-configuration on SSL.
But then this fix has been done: https://trac.nginx.org/nginx/ticket/178
Basically with this, validation of the configuration is done during nginx startup, that will refuse to start with invalid configuration on SSL. Consequently, all related tests are failing with a sufficiently up-to-date nginx. For now, it is not seen on Travis because Ubuntu Trusty is used, with an old Nginx.
The PR fixes that, by generating on the fly self-signed certificates in the two impacted tests, and pushing the right parameters in the Nginx configuration.
* Fix nginx configuration with self-signed certificates generated on the fly
* Fix lint/mypy
* Fix old cryptography
* Unattended openssl
* Update lock_test.py
So merging the study from @bmw and me, here is what happened.
Each invocation of `certbot.logger.post_arg_parse_setup` create a file handler on `letsencrypt.log`. This function also set an atexit handler invoking `logger.shutdown()`, that have the effect to close all logger file handler not already closed at this point. This method is supposed to be called when a python process is close to exit, because it makes all logger unable to write new logs on any handler.
Before #6667 and this PR, for tests, the atexit handle would be triggered only at the end of the pytest process. It means that each test that launches `certbot.logger.post_arg_parse_setup` add a new file handler. These tests were typically connecting the file handler on a `letsencrypt.log` located in a temporary directory, and this directory and content was wipped out at each test tearDown. As a consequence, the file handles, not cleared from the logger, were accumulating in the logger, with all of them connected to a deleted file log, except the last one that was just created by the current test. Considering the number of tests concerned, there were ~300 file handler at the end of pytest execution.
One can see that, on prior #6667, by calling `print(logger.getLogger().handlers` on the `tearDown` of these tests, and see the array growing at each test execution.
Even if this represent a memory leak, this situation was not really a problem on Linux: because a file can be deleted before it is closed, it was only meaning that a given invocation of `logger.debug` for instance, during the tests, was written in 300 log files. The overhead is negligeable. On Windows however, the file handlers were failing because you cannot delete a file before it is closed.
It was one of the reason for #6667, that added a call to `logging.shutdown()` at each test tearDown, with the consequence to close all file handlers. At this point, Linux is not happy anymore. Any call to `logger.warn` will generate an error for each closed file handler. As a file handler is added for each test, the number of errors grows on each test, following an arithmetical suite divergence.
On `test_sdists.py`, that is using the bare setuptools test suite without output capturing, we can see the damages. The total output takes 216000 lines, and 23000 errors are generated. A decent machine can support this load, but a not a small AWS instance, that is crashing during the execution. Even with pytest, the captured output and the memory leak become so large that segfaults are generated.
On the current PR, the problem is solved, by resetting the file handlers array on the logging system on each test tearDown. So each fileHandler is properly closed, and removed from the stack. They do not participate anymore in the logging system, and can be garbage collected. Then we stay on always one file handler opened at any time, and tests can succeed on AWS instances.
For the record, here is all the places where the logging system is called and fail if there is still file handlers closed but not cleaned (extracted from the original huge output before correction):

This PR reactivates tls-sni-01 challenges on recent Boulder versions checkout for integration tests. This allows to continue testing this challenge until it is officially dropped from server (Boulder) and client (Certbot).
Reverts #6679.
* Remove tls-sni-01 challenges in integration tests
* Remove the tls-sni test in the less invasive way
* Correct code coverage from tls-sni logic not been tested anymore.
* Update certbot-boulder-integration.sh
In response to #5342.
Currently, certbot will execute the operations necessary to validate a challenge even if the challenge has already been validated before against the acme ca server. This can occur for instance if a certificate is asked and issue correctly, then deleted locally, then asked again.
It is a corner case, but it will lead to some heavy operations (like updating a DNS zone, or creating an HTTP server) that are not needed.
This PR corrects this behavior by not executing challenges already validated, and use them directly instead to issue the certificate.
Fixes#5342
* Avoid to execute a given challenge that have been already validated by acme ca server.

Stop caching the results of ipv6_info in http01.py. A call to choose_vhosts might change the ipv6 results of later calls. Add tests for this and default_listen_addresses more broadly.
Previously, Nginx did not allow `${` to start a variable name. Now it's allowed to. This means we'll be more permissible than Nginx when people are on older versions of Nginx, but it's unlikely anyone was relying on this to fail in the first place, so that's probably ok.
This makes errors more useful when Nginx can't be found or when Nginx's
configuration can't be found. Previously, a generic
`NoInstallationError` isn't descriptive enough to explain _what_ wasn't
installed or what failed without going digging into the source code.
