Fix teardown for Java integration tests

3ee8a59c made ZK ports non-global which broke teardown in Java
integration tests. This is because the Java integration test helper
does not keep track of the ports assigned to ZK between setup and
teardown calls. This change makes sure that port assignment is called
exactly once during setUp and tearDown.

dbconfigs: remove defaults, they cause confusion.

DB config defaults are a source of confusion. It's better

This CL removes the few places that are not.
