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
