This is to keep the connection alive on tablet to keep holding the lock that the current session hold.
Heartbeat will get triggered only if the session is active i.e. it receives a query for execution and also based on when the last time heartbeat was sent to tablet (currently it is 5 sec).
This is put under a flag
