One push deploys

This will make it so the monitor will exit on completion of the deploy that was executed.  It will exit with a non-zero exit status if the deploy failed, otherwise it will exit normally.

It should be noted that this is hooking up a second poller to the monitor (conditionally) that does the exact same API call that is done to populate the data for the monitor.  There might be a clever way that I can share that data, but it was too nested in the spies and such of the monitor lib to try and do so for this feature.  I fully expect that AWS can handle the traffic though.
`completion` :trollface:
