Define OS options by a dedicated object in Apache configurator (#8778)
In https://github.com/certbot/certbot/pull/8748#discussion_r605457670 we discussed about changing the dict used to set OS options for Apache configurators into a dedicated object.

* Create _OsOptions class to configure the os specific options of the Apache configurators

* Fix tests

* Clean imports

* Fix naming

* Fix compatibility tests

* Rename a class

* Ensure restart_cmd_alt is set for specific OSes.

* Add docstring

* Fix override

* Fix coverage
