Beryllium: circular dependency on Controller

Autorelease jobs now require cycle-free pom dependecies. Mdsal is now breaking Beryllium autorelease.
Beryllium is not actively maintained anymore, but autorelease should be ready in case a security fix is needed.

The offending POM modules are:

• dom/sal-test-model/pom.xml: Parent set as sal-parent, should be easy to migrate to a mdsal-located parent.
• dom/mdsal-artifacts/pom.xml: Contains many controller artifacts, should be trimmed-down to mdsal artifacts only. Also, groupId should not be controller (this may require changes to other projects).
