What does this MR do?

Adds support to upload and download maven packages from GitLab.

I tested upload with for both mvn deploy and mvn release:perform.
EEP feature; must be enabled in config
Uses workhorse file upload
Should be compatible with object storage

Why was this MR needed?

So people can add GitLab to their pom.xml file and upload/download packages from GitLab
