TestTxnCommands2.testMultiInsertStatement is failing for map reduce error, not related to
this patch. Local run is passing.

TestMiniDruidCliDriver.testCliDriver and spark.client.rpc.TestRpc.testServerPort are not

> The transactions opened by applying EVENT_OPEN_TXN should never be aborted automatically
due to time-out. Aborting of transaction started by replication task may leads to inconsistent
state at target which needs additional overhead to clean-up. So, it is proposed to mark the
transactions opened by replication task as special ones and shouldn't be aborted if heart
beat is lost. This helps to ensure all ABORT and COMMIT events will always find the corresponding
txn at target to operate.
