HONEYCOMB-405 - Revert fix for indirect updates
If indirect update(delete+create) fails in a way, that delete passed, but update part failed, delete part must be reverted Moves reverter creation to MDTG and test cases related too it to ModifiableDataTreeDelegatorRevertTest Fixes tracking of allready processed changes by tracking them from perspective of processModifications() method Introduces UpdateFailedException as replacement for BulkUpdateException(now thrown also for single updates) Separates ReverterImpl from FlatWriterRegistry and ads unit tests Change-Id: If0066d0716d9476be89b1d99985b6745becac15e Signed-off-by: Jan Srnicek <jsrnicek@cisco.com>
