Ansible Keepalived Versions Save

This release include two new features:

• Support for virtual mac addresses, by @jimbali
• Only reload config if it has changed, by @gurubert

(Not very) fun story: Using reload instead of restart for keepalived was one of the first features in this role. Interestingly enough, it didn't appear in the first publicly released version of this role. When releasing this role, many people didn't care anymore about reload vs restarts, so the role regressed. I am glad @gurubert cared, as I feel the role is closer to its original goals :). Thanks @gurubert .

This release is removing the support of old distributions, cleans up some code, and introduce a different way to test things.

You can now easily see, with github actions, what's going on in the role, for the multiple distributions, thanks to docker/molecule/tox.

Let's go for 5 more years!

Added fixes from @spookiej and @noonedeadpunk

Includes a fix done by @noonedeadpunk , to ensure the keepalived service is always on, even if it was masked before the role runs.

New feature, dont_track_primary, by M1ha-Shvn

New feature from @elcomtik: Add a boolean to change the systemd overrides, to have a restart "always" mode for keepalived. Thank you @elcomtik !

Fix from @pugnacity: Removed hardcoded list of packages in tasks, which were defined in the vars.

New feature: virtual_ipaddress_excluded, by @tridde. Thank you!

Thanks to @thehawkes , we now have split the template to ease the edits of the templates in the future.

While there is no change in the user interface of the configuration (the dictionary stays the same), and the templated configuration should not have changed (the generated template stays the same with the same input), I think the change is large enough for people to warrant a .Y. bump in the release version, as it is effectively a new feature to split the templates, and it might surprise people.

Thanks to @thehawkes , we know have extra real_server options. New features, new .Y. version!
