Now, when you call PopWorker(), it finds an idle one or creates a worker. If a new worker is created, the worker is associated to the request and can only be used by it.

This PR decouples the worker creation and the worker-to-task assignment, by adding an abstraction namely PopWorkerRequest. Now, if a req triggers a worker creation, the req is put into a queue. If there are workers ready, that is a PushWorker is called, either from a newly started worker or a released worker, Ray matches the first fitting request in the queue. This reduces latency.

Later it can also be used to pre-start workers more meaningfully.

Now, when you call PopWorker(), it finds an idle one or creates a
worker. If a new worker is created, the worker is associated to the
request and can only be used by it.

This PR decouples the worker creation and the worker-to-task assignment,
by adding an abstraction namely PopWorkerRequest. Now, if a req triggers
a worker creation, the req is put into a queue. If there are workers
ready, that is a PushWorker is called, either from a newly started
worker or a released worker, Ray matches the first fitting request in
the queue. This reduces latency.

Later it can also be used to pre-start workers more meaningfully.
