Reduce deployment footprint

A number of large artifacts are deployed, but not intended to be reused from other projects. They have a disproportionate overhead on deployment.

The artifacts involved are

• hippo-cms-translation-test
• hippo-cms-xinha-test
• hippo-package-cms-ear

If this needs to be backported to older branches; the following artifacts should also be considered

• hippo-package-cms-war
