ISPN-2483 State transfer issue with the transactions for which the originator has crashed

Remove StaleTransactionCleanupService and clean the stale transactions
explicitly from StateConcumerImpl.onTopologyUpdate, after applying any
transferred transactions.

Since now it's more likely to have stale transactions on the provider,
the provider also checks if the originator has left the cache before
sending a transaction.
ISPN-2778 When a cache is restarted, the LEAVE and JOIN commands are not ordered

Make the LEAVE command synchronous. Since the cache start/shutdown is
already synchronized, this will prevent the cache from restarting before
the coordinator has removed it from the members list.
ISPN-2768 - Write new tests for Query module

  * New tests are added to Infinispan Query module testing Clustered Queries;
  * New tests are added for testing Queries on Topology Aware nodes;
  * New tests are added testing programmatic configuration for mass indexers;
