New interfaces for binding control

[viniciusccarvalho]

Provide a couple of new interfaces that binders may implement:

public interface Seekable {
   boolean seek(Long offset);
}

public interface Resumable
  boolean pause();
  boolean play();
}

Those two interfaces will be exposed via Actuator endpoints for users to play/pause/seek consumers

Implementations may reuse the lifecycle methods start/stop, but it may not be the case.

Start/Stop still plays a role for producers if setting autoStartEnabled

play() should be resume(), and I'd argue that the interface should be Pausable since you first have to pause before you can resume ;)
