> TaskManagerRunner  has a close method，but did not call when it stop.
> Some resources in TaskManagerRunner come with ShutdownHook, but some resources do not, such as rpcSystem, which causes the temporary file flink-rpc-akka_*.jar to not be deleted when stop.
> Should TaskManagerRunner need a ShutdownHook to call the close method to release all resources
