0324d1740e Ensure relpath is executed on paths in the same drive (#7335)
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.

d5de24d9fc [Windows] Security model for files permissions - STEP 2 (#6895)
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.

* Add executable permissions

* Add the delegate certbot.compat.os module, add check coding style to enforce usage of certbot.compat.os instead of standard os

* Load certbot.compat.os instead of os

821bec6997 Remove tls-sni related flags in cli. Add a deprecation warning instead. (#6853)
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

Update parser to match new Nginx functionality (#6381)
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.
