> 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.

> handles `ReconnectResourceManager`.
