Create Arch.yml

Fixes #189

@C0rn3j : I think you should extend the molecule tests in this role to test the role against an arch container. I did something similar with Rocky Linux 9. You may get inspiration from here: https://github.com/geerlingguy/ansible-role-postgresql/pull/224/files

@C0rn3j : No interest in fully implementing Arch Support?

[C0rn3j]

@geerlingguy How would I go about testing against my own image?

I see that the molecule tests try against your own repository but you do not have one set up for Arch Linux.

I was able to write a bare Dockerfile for Arch to be included in your repo, but was not able to properly test it.

Also am unsure why initctl_faker and rsyslog are there.

I would like to get Arch Linux supported here (and add tests to a couple other roles too), but right now I'm just marking some issues as planned that I'd like to get to but can't yet. I would be glad to add on an archlinux testing image, though it seems Arch likes to update things quite rapidly, so maintenance (where I like to stick to a particular version, like RHEL 7/8/9) could be a bit weird.

[geerlingguy]

Alternatively, since Arch is a little weird in that regard, I'd be willing to merge this change without adding archlinux to the testing suite (for now at least... we'll see how maintenance goes long term). But please do add it in the listing for supported distros in the meta/main.yml file.

[C0rn3j]

I've dropped the test and added the meta.yml entry for now.

I think the problematic things with these minimal images would most likely be the systemd hacks, since in my Dockerfile I used pip to install Ansible itself, so it should hopefully mostly be the same as other distros.
