[FLINK-6341]Don't let JM fall into infinite loop
When TaskManager register to JobManager, JM will send a
"NotifyResourceStarted" message to kick off Resource Manager, then trigger a
reconnection to resource manager through sending a
"TriggerRegistrationAtJobManager".
When the ref of resource manager in JobManager is not None and the
reconnection is to same resource manager, JobManager will go to a infinite
message sending loop which will always sending himself a
"ReconnectResourceManager" every 2 seconds.
We have already observed that phonomenon. More details, check how
JobManager handles `ReconnectResourceManager`.
