watcher: Expose isClosed method

[giri-vsr]

Expose isClosed method on watcher so that we can restart the watch incase it is closed because of Errors.isHaltError(status) or Errors.isNoLeaderError(status)

@lburgazzoli can you please check this?

[lburgazzoli]

@giri-vsr it would be nice to add a test

[giri-vsr]

@lburgazzoli Thanks. Test and method already exists. Just exposing isClosed method.

Now I have updated the test to access isClosed without casting
