Description
Currently scheduling for a node is done when a node heartbeats.
For large cluster where the heartbeat interval is set to several seconds this delays scheduling of incoming allocations significantly.
We could have a continuous loop scanning all nodes and doing scheduling. If there is availability AMs will get the allocation in the next heartbeat after the one that placed the request.
