Version Endpoint [GONRG-2681]

I'd like to propose a new endpoint for all services to retrieve the version information. I'm most interested in the tag version / upcoming tag version. My thinking is maven-centric, but I'd like to get the artifact version injected into the jar files and available via a simple GET endpoint.

I have several use cases in mind right now:

1. The end customer should have a way to query their environment to know what versions they are running. Then they would know that patches they see coming in on community have been applied to their environment. The Admin UI may be able to use this endpoint to make that query easier.
2. Application developers would be able to query versions of the services they are working with to determine compatibility.
3. The CI pipeline can query the running instances of dependent services, and issue a warning if the major/minor doesn't match the currently executing one. Have branch names or commit hashes would further improve this, but isn't part of my initial thinking.

What complexities and challenges do you see in trying to provide this information?
