ISPN-4487 Force OSGi test execution order
ISPN-4486 Map/Reduce DefaultCollector needs to be synchronized in certain use cases
ISPN-4482 Upgrade JGroups to 3.5.0.Beta9
ISPN-4154 Cancelled segment transfer causes future entry transfer to be ignored

Stop tracking keys when a new coordinator cancels the state transfer.
ISPN-4469 StateConsumerImpl segment change tracing is incorrect
ISPN-4479 Remote executor thread pool configuration is ignored
ISPN-4481 Use UNICAST3 and NAKACK2 in the default server configuration
ISPN-4484 Outbound transfers can be cancelled by old CANCEL_STATE_TRANSFER command
Filter logs for failed setup methods as well as tests
ISPN-4426 Transaction replayed but not committed

Move the transaction replay check inside TxInterceptor to avoid concurrency
issues (since TransactionSynchronizerInterceptor synchronizes on the tx).

TEST_PING needed some changes, as MERGE3 doesn't trigger Discovery.findMembers()
Smaller timer pool and queue.
