Use distro library for all OS version detection (#7467)

This pull request ensures that we use distro package in all the distribution version detection. It also replaces the custom systemd /etc/os-release parsing and adds a few version fingerprints to Apache override selection.

Fixes: #7405

* Revert "Try to use platform.linux_distribution() before distro equivalent (#7403)"

This reverts commit ca3077d034.

* Use distro for all os detection code

* Address review comments

* Add changelog entry

* Added tests

* Fix tests to return a consistent os name

* Do not crash on non-linux systems

* Minor fixes to distro compatibility checks

* Make the tests OS independent

* Update certbot/util.py
