ISPN-4400 Takes a long time to start up all clusters which has a lot of segments

This is mainly caused by the myriad of internal copies performed by the CopyOnWriteArraySet used in InboundTransferTask for tracking the segments being requested during ST. This collection is updated way too frequently if we have a large number of segments. It seems that using a simple HashMap and doing external synchronization works better both in terms of time and memory.
ISPN-3959 JdbcBinaryStore's expiration locks buckets indefinitely
Added call for PurgeListener to LevelDBStore
ISPN-4401 OSGi - PAX-URL needs to work when the local mvn repo is passed from a configuration file
ISPN-3530 ISPN-1855 Keep per-cache CH to route requests correctly

* It fixes an issue where accessing non-distributed caches can
break topology updates.
* Add asymmetric routing test that forces each server to hash
only to itself to replicate situations where different distributed
caches have different CH.
ISPN-3840 Test suite should continue when a test hasn't closed its cache managers

Add fail-all-tests and fail-all-tests-setup profile to fail all the tests
and @Before methods and check that their cache managers are closed properly.
ISPN-1951 Use MERGE3 in the default UDP configuration

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