add dnfmodule repo implementation

This is a new one for me:

        	broken groups or modules: nodejs:18
       	Error: /Stage[main]/Nodejs::Repo::Dnfmodule/Package[nodejs dnf module]/ensure: change from 'purged' to '18' failed: Could not update: Execution of '/usr/bin/dnf module install -d 0 -e 1 -y nodejs:18' returned 1: Error: Problems in request:
       	broken groups or modules: nodejs:18

[evgeni]

It started once I dropped the enable_only 🤔

[ekohl]

It made me look it up: enable_only makes it dnf module enable instead of dnf module install (https://github.com/puppetlabs/puppet/blob/5dae3b1f808d4fe0def1c5673c65273d2466ff43/lib/puppet/provider/package/dnfmodule.rb#L88-L103). I guess that doesn't work for the nodejs module.

[ekohl]

And there is code that should catch that error, but looks like that doesn't work.

[evgeni]

Modules really, really, should never be installed (it was a mistake to allow that). (end-of-rant)

[evgeni]

And there is code that should catch that error, but looks like that doesn't work.

The match is: /^(?:missing|broken) groups or modules: #{Regexp.quote(@resource[:name])}$/, so in our case: ^broken groups or modules: nodejs$, but the output is "… nodejs:18".

I think the match should be /^(?:missing|broken) groups or modules: #{Regexp.quote(args)}$/ instead

Yeah, using 389-ds from the original ticket, I see:

# dnf module install -d 0 -e 1 -y 389-ds
Error: Problems in request:
broken groups or modules: 389-ds

# dnf module install -d 0 -e 1 -y 389-ds:1.4
Error: Problems in request:
broken groups or modules: 389-ds:1.4

# dnf module install -d 0 -e 1 -y 389-ds:1.4/sdf
Error: Problems in request:
missing groups or modules: 389-ds:1.4/sdf

[evgeni]

also, no idea why exactly 18 has no default profile:
