Fixes #7115 This PR creates a `realpath` method in `filesystem`, whose goal is to replace any call to `os.path.realpath` in Certbot. The reason is that `os.path.realpath` is broken on some versions of Python for Windows. See https://bugs.python.org/issue9949. The function created here works consistently across Linux and Windows. As for the other forbidden functions in `os` module, our `certbot.compat.os` will raise an exception if its `path.realpath` function is invoked, and using the `os` module from Python is forbidden from the pylint check implemented in our CI. Every call to `os.path.realpath` is corrected in `certbot` and `certbot-apache` modules. * Forbid os.path.realpath * Finish implementation * Use filesystem.realpath * Control symlink loops also for Linux * Add a test for forbidden method * Import a new object from os.path module * Use same approach of wrapping than certbot.compat.os * Correct errors * Fix dependencies * Make path module internal
