Add basic tests using packit

[ekohl]

The aim of this is to run tests on the built RPM to verify various scenarios using real systems.

Why does this file get removed?

[ekohl]

Note it's in the last [WIP] commit. Just to avoid spending extra cycles just iterating on something unrelated.

[ekohl]

I opened teemtee/tmt#2825 for some guidance on best practices for repository handling.

[ekohl]

@Griffin-Sullivan locally I could run this with tmt run -a provision -h container -i centos:stream9 or tmt run -a provision -h virtual -i c9 for either a container or a VM. Afterwards you can run tmt run -l report -vvv to get all the output from the last run.

[ehelms]

Do you know why --help triggers hostname?

[ekohl]

No. It's either this:

foreman_maintain/lib/foreman_maintain/concerns/system_helpers.rb

Lines 94 to 96 in cfbb8c4

	def hostname
	execute('hostname -f')
	end

But more likely this:

foreman_maintain/lib/foreman_maintain/config.rb

Line 24 in cfbb8c4

@foreman_url = @options.fetch(:foreman_url, `hostname -f`.chomp)

That latter should really use block form:

@foreman_url = @options.fetch(:foreman_url) { `hostname -f`.chomp }

That way it doesn't execute hostname -f if a value is found.

[ehelms]

You could, in theory, use this PR to test both this PR and the theory? By including these pieces of code selectively commented out and removing the hostname requires. Kind of a fun experiment.

#819. And there's already plenty of other things I'm trying to test. First I just want it to work.

[ekohl]

It's failing to install. I suspect it's trying to install the package before the repository with our packages is set up.
