<description>
Enforces our invariants for the test client modules.
E.g. that modules have a specific set of transitive dependencies
and shaded artifacts only contain classes that are in particular
packages. Does the enforcement through the maven-enforcer-plugin
and an integration test.

Check that we actually relocated everything we included.
It's critical that we don't ship third party dependencies that haven't
been relocated under our pacakge space, since this will lead to
difficult to debug classpath errors for downstream. Unfortunately, that
means inspecting all the jars.
