> Currently, {{ResourceManager#internalDeregisterApplication}} is a blocking 
> call, so all the specific deployment implementation will do the Flink cluster 
> deregister synchronously. 
> After FLINK-17024, we could get a safe thread pool to execute the I/O 
> operations, including the "deregister". This ticket is to make the interface 
> asynchronous. Benefit from this, the shutdown process will be a little 
> faster.
