Currently integration tests against Boulder fail during nightly tests. See https://travis-ci.com/certbot/certbot/builds/115373954.
This is due to a failure to cleanup the workspace associated to the Boulder docker started during the integration tests. Indeed this docker compile several artifacts whose owner is root, and permissions are 0744. These files are persisted in the workspace folder attached to the Docker.
Since tox is run as a non-root user (but this user still have access to the Docker daemon), everything works fine until the end of the test suite, when all resources are cleaned up. At this point, pytest fires a PermissionError when failing to delete these artifacts, return with a non-zero exit code, and so fail the build.
Since this situation could happen outside of the CI, I made appropriate corrections to allow the integration tests to be run as a non-root user, instead of changing Travis to execute tests as root user.
The correction is to add a step to the cleanup process: the deletion of these artifacts through an ad-hoc docker instance.
During review of #6989, we saw that some of our test bash scripts were still used in the Boulder project in particular. It is about `tests/integration/_common.sh` in particular, to expose the `certbot_test` bash function, that is an appropriate way to execute a local version of certbot in test mode: define a custom server, remove several checks, full log and so on.
This PR is an attempt to assert this goal: exposing a new `certbot_test` executable for test purpose. More generally, this PR is about giving well suited scripts to quickly make manual tests against certbot without launching the full automated pytest suite.
The idea here is to leverage the existing logic in certbot-ci, and expose it as executable scripts. This is done thanks to the `console_scripts` entry of setuptools entrypoint feature, that install scripts in the `PATH`, when `pip install` is invoked, that delegate to specific functions in the installed packages.
Two scripts are defined this way:
* `certbot_test`: it executes certbot in test mode in a very similar way than the original `certbot_test` in `_common.sh`, by delegating to `certbot_integration_tests.utils.certbot_call:main`. By default this execution will target a pebble directory url started locally. The url, and also http-01/tls-alpn-01 challenge ports can be configured using ad-hoc environment variables. All arguments passed to `certbot_test` are transferred to the underlying certbot command.
* `acme_server`: it set up a fully running instance of an ACME server, ready for tests (in particular, all FQDN resolves to localhost in order to target a locally running `certbot_test` command) by delegating to `certbot_integration_tests.utils.acme_server:main`. The choice of the ACME server is given by the first parameter passed to `acme_server`, it can be `pebble`, `boulder-v1` or `boulder-v2`. The command keeps running on foreground, displaying the logs of the ACME server on stdout/stderr. The server is shut down and resources cleaned upon entering CTRL+C.
This two commands can be run also through the underlying python modules, that are executable.
Finally, a typical workflow on certbot side to run manual tests would be:
```
cd certbot
tools/venv.py
source venv/bin/activate
acme_server pebble &
certbot_test certonly --standalone -d test.example.com
```
On boulder side it could be:
```
# Follow certbot dev environment setup instructions, then ...
cd boulder
docker-compose run --use-aliases -e FAKE_DNS=172.17.0.1 --service-ports boulder ./start.py
SERVER=http://localhost:4001/directory certbot_test certonly --standalone -d test.example.com
```
* Configure certbot-ci to expose a certbot_test console script calling certbot in test mode against a local pebble instance
* Add a command to start pebble/boulder
* Use explicit start
* Add execution permission to acme_server
* Add a docstring to certbot_test function
* Change executable name
* Increase sleep to 3600s
* Implement a context manager to handle the acme server
* Add certbot_test workspace in .gitignore
* Add documentation
* Remove one function in context, split logic of certbot_test towards capturing non capturing
* Use an explicit an properly configured ACMEServer as handler.
* Add doc. Put constants.
Following discussion in #6947 (comment), I have second thoughts about relying on acme in certbot-ci.
Indeed, I think it is a good design to not rely in tests on the code you are testing. Obviously in unit tests it is very difficult, since most of the time the unit that is tested needs input generated by other part of the code. However it is not really a problem in a unit test, as its purpose is to make assertions about a specific portion of the code, not the others parts.
In the scope of integration tests, the software tested is treated as a black box. In this case, having some parts of the test logic that use in fact part of the code in the black box, increase the risk that some assertions compared two results coming from the same flawed logic from the tested software.
Since using acme in certbot-ci is only saving few lines of code, I think it does not worth the risk and the added complexity to declare acme as a dependency. I prefer to duplicate these lines and keep certbot-ci free of any dependency coming from the certbot project.

This PR is the part 4 to implement #6541. It adds the integration tests for the nginx certbot plugin, and corresponds to the certbot-ci translation of certbot-nginx/tests/boulder-integration.sh that is executed for each PR.
As with certbot core tests, tests are written in Python, and executed by pytest, against a dynamic Boulder/Pebble instance setup. Tests are parallelized, of course, and a specific IntegrationTestsContext class, extended the one from certbot core tests, is crafter for these specific tests: its main goal is to setup a specific nginx instance for the current test.
On top of that, I use the test parametrization feature of Pytest, to drastically reduce the size of the actual code: indeed, the 6 tests from the original bash script share the same logic. So using a parametrization, one unique test is written, that is then executed 6 times against 6 different sets of parameters.
Note that the module integration_tests.nginx_tests.nginx_config do the same, but in Python, than certbot-nginx/tests/boulder-integration.conf.sh. The latter will be removed in a future PR, with all other bash scripts.
