Commits on Aug 13, 2024

  1. Add to check the liveness for connection with controller 

    This adds a new heartbeat signal for internal DBus to controller, also
adds a new option to agent: ControllerHeartbeatThreshold.

The controller emits the heartbeat signal like agent. The agent writes
last seen timestamp for connection with controller if it receives the
heartbeat signal from controller, and the agent periodically checks the
last seen timestamp for connection with controller, and if it was sent
before ControllerHeartbeatThreshold, the agent treats it as
disconnected.

If ControllerHeartbeatThreshold value is 0, it is disabled to check the
liveness for connection with controller, and the default value is 0.
