I think we can have a HARPCGateway extends HAService which can be reused

> Implement TaskManager side of registration at ResourceManager
> -------------------------------------------------------------
>
> Key: FLINK-4355
> URL: https://issues.apache.org/jira/browse/FLINK-4355
> Project: Flink
> Issue Type: Sub-task
> Components: Cluster Management
> Reporter: Zhijiang Wang
> Assignee: Stephan Ewen
>
> If the {{TaskManager}} is unregistered, it should try and register at the
> {{ResourceManager}} leader. The registration messages are fenced via the
> {{RmLeaderID}}.
> The ResourceManager may acknowledge the registration (or respond that the
> TaskManager is AlreadyRegistered) or refuse the registration.
> Upon registration refusal, the TaskManager may have to kill itself.
