HIVE-18679 : create/replicate open transaction event
EVENT_OPEN_TXN:
Source Warehouse:
Create new event type EVENT_OPEN_TXN with related message format etc.
When any transaction is opened either by auto-commit mode or
multi-statement mode, need to capture this event.
Repl dump should read this event from EventNotificationTable and dump the
message.
Target Warehouse:
Repl load should read the event from the dump and get the message.
Open a txn in target warehouse.
Create a map of source txn ID against target txn ID and persist the same in
metastore. There should be one map per replication policy (DBName.* incase of
DB level replication, DBName.TableName incase of table level replication)
