Description

None of the AdaptiveScheduler states return JobStatus#CREATED when requestJobStatus() is called. This violates the job state machine, and makes it a bit difficult to setup job state timestamps in the AdaptiveScheduler (FLINK-24775).

We are in the INITIALIZING state from Created -> WaitingForResources -> CreatingExecutionGraph, and then switch straight to RUNNING in Executing.

It is tricky to retain the same semantics for the Default and AdaptiveScheduler, but I think it would be fine to return CREATED once we reached WaitingForResources because from the users-perspective it behaves similarly.
