Use MIMA

Solves #217

A rough draft how could it look like, but I see a big influence of shrinkwrap, hence, IMHO this could be radically simplified.

Also, unsure is "LocalRepository" layrri specific (I guess it is), but just FYI: new feature of resolver is "chained local repository", so it is able to use multiple maven local repositories as well, might be worth to factor it in.

FWIW local repository is just a dir with JARs with or without POMs. We need this option to resolve JARs when network is not available. There may not be POMs nor maven-metadata.xml and that's fine.

Hm, it seems GH env gets detected and as those things are at "standard places" MIMA tries (and fails) to decrypt them?

Failed to decrypt password for server github: org.sonatype.plexus.components.sec.dispatcher.SecDispatcherException: java.io.FileNotFoundException: /home/runner/.m2/settings-security.xml (No such file or directory) @ server: github

My assumption (unverified):

• settings.xml discovered by MIMA has github credentials encrypted
• there is no settings-security.xml present, hence MIMA fails
• it is telling that in module layrry-integrationtest-runner I see no settings.xml at all (hence I believe this is GH Maven env settings that is being discovered)

@aalmiray can you confirm?
