Title: Catch ConnectionError in client and return human friendly message.

This was brought up in [a comment](https://github.com/opdemand/deis/pull/374#issuecomment-31684010) on #374. I'm sure we've all seen it a few times ourselves too. So basically it's just a more useful way of saying that the client can't reach the Controller.
