Xintong Song created FLINK-14189:
------------------------------------

             Summary: Extend TaskExecutor to support dynamic slot allocation
                 Key: FLINK-14189
                 URL: https://issues.apache.org/jira/browse/FLINK-14189
             Project: Flink
          Issue Type: Sub-task
            Reporter: Xintong Song


* TaskSlotTable
 ** Bookkeep task manager available resources
 ** Add and implement interface for dynamic allocating slot (with resource profile instead of slot index)
 ** Create slot report with dynamic allocated slots and remaining available resources
 * TaskExecutor
 ** Support request slot with resource profile rather than slot id.

The slot report still contain status of legacy free slots. When ResourceManager requests slots with slot id, convert it to default slot resource profiles for bookkeeping.
