> It is part of work for Flip-6.
> The {{HeartbeatManager}} is mainly used for monitoring heartbeat target and reporting
payloads.
> For {{ResourceManager}} side, it would trigger monitoring the {{HeartbeatTarget}} when
receive registration from {{TaskManager}}, and schedule a task to {{requestHeartbeat}} at
interval time. If not receive heartbeat response within duration time, the {{HeartbeatListener}}
will notify heartbeat timeout, then the {{ResourceManager}} should remove the internal registered
{{TaskManager}}.
> For {{TaskManger}} side, it would trigger monitoring the {{HeartbeatTarget}} when receive
registration acknowledgement from {{ResourceManager}}. An it will also be notified heartbeat
timeout if not receive heartbeat request from {{ResourceManager}} within duration time.
> The current implementation will not interact payloads via heartbeat, and it can be added
if needed future.
