[FLINK-5856] return redundant containers to yarn for yarn mode
This pr is for
jira-#[5856](https://issues.apache.org/jira/browse/FLINK-5856)
The yarn AMRMClient used for requesting containers from yarn in flink has
its own defects:
It need to remove container requests after container returned, or else the
requests will be sent again.
Even so, it doesn't guarantee that the number of containers return is
exactly equal to the number requested.
So need to release the redundant containers returned for yarn mode as we
ask for containers according to the need of a job.
