Provide means to release a single module

[mp911de]

We should support releasing a single module outside the regular release train. The release should either happen from an existing maintenance branch or the master branch with the following actions included:

• Switch artifact version to non-snapshot
• Update changelog
• Build and deploy the artifact
• Increment version
• On minor/major releases: Create maintenance branch with accordingly incremented version

Activity around release tickets, re-inclusion into release train (e.g. version increment in BOM and release tooling) is not in the scope of this ticket.
