## What is the purpose of the change
This PR is to unify slot request timeout handling for streaming and batch
tasks regarding whether the slot will be occupied indefinitely.
It is a pre-requisite of bulk slot allocation so that we do not need to
maintain 2 different slot timeout handling.
## Brief change log
See commits.
## Verifying this change
- *Added unit tests for slot occupation*
- *Existing SlotPoolBatchSlotRequestTest and
SlotPoolPendingRequestFailureTest help to verify the change on batch and
streaming jobs*
