Add option to generate setfile with multiple hosts and roles

[h-haaks]

We have a few modules that override the modulesync generated ci.yml because they have integration tests that require multiple hosts with custom roles.
This PR add a new option to metadata2gha that can be used to generate setfile strings to bring up multiple hosts in gha.

code looks fine to me, but I would like to see another reviewer.

I didn't notice #111 until now ...
If we change my string format from '#HOST:ROLE,ROLE' to 'HOSTNAME:ROLE,ROLE' we could solve both hostname and role requirements.

ie gen strings like this for 'myhost1:role1;myhost2;role2'
`debian12-64role1.ma{hostname=myhost1-puppet7}-debian12-64role2.a{hostname=myhost2-puppet7}

Rename option to --beaker_hosts_and_roles ? or even just --hosts and leave it up to docs that roles are also supported.

[h-haaks]

I think we could just keep roles as a string. no need to split it into array.

I'll squash my commits before merge.

@bastelfreak do I wait for @ekohl to approve before merging?

[ekohl]

Currently traveling, so I didn't take too close of a look but at first glance it looks sensible.

@jhoblitt would this also serve your needs?

I haven't tried it but at a glance I think it would work for me with changes to gha-puppet & modsync_config.

I put up a branch in puppet-mongodb to verify that my changes are working as expected
voxpupuli/puppet-mongodb#752

Ah, I'll have to do something in modulesync_config as well to get my new input from .sync.yml to ci.yml
Or is there a chance voxpupuli/modulesync_config#858 will get approved?

[h-haaks]

I haven't tried it but at a glance I think it would work for me with changes to gha-puppet & modsync_config.

modulesync_config support fixed in version 7.5.0 (voxpupuli/modulesync_config#888)
gha-puppet voxpupuli/gha-puppet#53 will be merged and gha-puppet released when this is merged.

@ekohl @bastelfreak is it ok to merge and release this now?
