ISPN-4519 Prepare should be broadcasted to entire cluster in replicated mode

Command should be sent to null even if not all caches are members
ISPN-4517 RollbackCommands should ignore leavers
ISPN-4484 fix caused unnecessary InterruptedExceptions

When state transfer is over, the response to the last StateResponseCommand
could reach the provider node after the CH_UPDATE from the coordinator.

If that happens, no data is lost, but the OutboundTransferTask thread is
interrupted and it logs the InterruptedException stack trace.
ISPN-4552 Upgrade H2 driver to 1.4.180
ISPN-4550 JpaStoreOOMETest.testProcessClear always fails

* store the data in disk to avoid OOME
ISPN-4504 Topology id is not properly set on ClusteredGetCommands

ClusteredGetCommand should NOT be topology-aware
ISPN-4503 Commands with topology id 0 are not properly ignored on joiners
ISPN-2522 The StateTransferCacheLoaderFunctionalTest (StateTransferFunctionTest) tests fail periodically

* Disable synchronizations, so that commit failures are not ignored.
* Pause between writes so that the writing thread doesn't hog all
  the CPU before the 2nd node joins.
* Fail-fast in StateTransferLargeObjectTest
ISPN-4522 Test for HR PLAIN auth against LDAP
ISPN-4545 Checkstyle line termination check should work on Windows
ISPN-4317 Optimize server test suite
 * all tests for remote queries use the same server
 * removed unnecessary test cases for the suppress-state-transfer tests and merged hotrod and memcached cases
 * merged single-node jdbc tests
 * added proper server killing (a small arquillian extension by Martin which was forgotten during the migration)
 * moved the Unstable category from class level to the failing method in ExampleConfigsTests
 * removed some server starts from TransportStackConfigurationIT test
ISPN-4551 RestStore parallel iteration fails for non-string keys if UTF-8 is not the default charset
A more sensible null check
Remove usages of deprecated SearchManager.getQueryFactory()
ISPN-4464 Unify test suite for remote and embedded DSL based query tests

Remote and embedded DSL query tests share the domain model. The model defines interfaces
that are implemented using Hibernate Search anontated entities for embedded mode and
Protobuf entities for remote mode. The test driver code is shared between embedded
and remote tests.
ISPN-4510 Enable configuring Transport instance via new XML parser
ISPN-4562 Upgrade to Hibernate Search 5.0.0.Alpha5
ISPN-1951 Use MERGE3 in the default UDP configuration
ISPN-4570 Remove UFC from JGroups TCP configurations
ISPN-3937 Investigate the memory usage of JDBC cache stores when processing a large result set

* Set the result type to TYPE_FORWARD_ONLY and the concurrency to CONCUR_READ_ONLY
* For the particular case of MySQL, setting the fetchSite to MIN_VALUE will fetch
a single row at the time
