Introduce test to prove PersistentCacheFactory can be overridden
Gerrit persistent cache defaults to an H2 implementation, which is
bound at start up via the sys injector.
Change-Id I7562b210fa introduced the ability to override this binding by
the usage of the CacheImpl annotation, however no tests were provided to
prove this behavior.
Introduce an integration test to ensure a different
PersistenCacheFactory implementation can indeed be bound.
Bug: Issue 10276
