Subject: [PATCH] Add Maven Build Cache plugin

The build cache extension caches the results of
maven goal executions and skips re-running them if
the same inputs are detected again.

This helps both local development (re run tests of
affected modules only) and CI builds eventually (a
subsequent commit will introduce sharing of the cache
between CI runs)
