This commit modifies InternalTestCluster to allow using client() and other operations inside a RestartCallback (onStoppedNode typically). Restarting nodes are now removed from the map and thus all methods now return the state as if the restarting node does not exist. This avoids various exceptions stemming from accessing the stopped node(s).
