Description
Use the heartbeat to register the Node.
Related to #9297.
Motivation and Context
Currently, the Node uses the NodeStatus event to register itself with the Distributor. Once it is registered, it fires the NodeHeartbeat event at a configurable regular interval to indicate it is alive. If the Distributor goes down and comes up again, the same Node will not re-register on its own since it fires the NodeStatus event to register only when it spins up. So the Node(s) will have to be restarted so they register again.
To fix this behaviour, the changes here use the NodeHeartBeat to register the node and indicate it is alive.
Thank you @diemol for helping me understand the issue and potential solution.
