GEODE-3519 servers are not locking on remove or invalidate ops initiated by clients
<p>
This test sets up two servers each with a client attached. The clients perform operations on
the same key in a region which, in the servers, has Scope.GLOBAL. There should be no conflation
and each operation should obtain a lock.
