remove any reference from configdocs till ISPN-3118 is implemented
enhanced the release script to also clear the release directory before every run
enhanced the release script to also make sure there is no locally modified  file
better logging of release progress
ISPN-3122 Allow ByteArrayEquivalence to be configured from XML
ISPN-1797 Implement MongoDB cache store
use a random database name in order to allow multiple test suites connecting to the same mongoDb instance
ISPN-3094 Cache.putForExternalRead in DIST transactional mode is not replicated to other members

* Refactor PutForExternalReadTest into a hierachy to test combinations of REPL/DIST mode and various tx modes.
* Move the non-transactional implementation from NonTxDistributionInterceptor.handleWriteCommand and supporting methods to BaseDistributionInterceptor.handleNonTxWriteCommand.
* TxDistributionInterceptor.handleWriteCommand no longer overrides the method from BaseDistributionInterceptor.
* Move all BaseDistributionInterceptor.visitXYZ methods to the tx/non-tx derived classes which now invoke either handleNonTxWriteCommand or handleTxWriteCommand, as needed. For PFER we always invoke handleNonTxWriteCommand.
* Move method visitPutKeyValueCommand() and supporting methods of non-tx locking interceptor to the common base class of the hierarchy so derived classes can delegate to super if PUT_FOR_EXTERNAL_READ flag is set. This ensures non-tx behaviour for PFER even if the actual interceptor instance is tx capable.
* These refactorings also fix ISPN-3114 because putForExternalRead is now handled in the non-tx code which no longer tries to cast the context to a TxInvocationContext.
Refactor BaseDistStateTransferConsistencyTest and BaseReplStateTransferConsistencyTest with their respective subclasses into a single class to include all tests

* The new tests now also cover distributed mode on join (previously only leave was tested for DIST mode).
* DistStateTransferOnJoinConsistencyTest.testReplacePessimistic fails due to ISPN-3095.
ISPN-3095 Cache.replace() succeeds on originator but fails randomly on remote owners during state transfer in DIST mode with pessimistic locking

* TxDistributionInterceptor.ignorePreviousValueOnBackup() should return true also for pessimistic case
* This makes DistStateTransferOnJoinConsistencyTest.testReplacePessimistic() pass
Remove unused dependencies
