Support Hipache automatically - Work in Progress / For discussion

Here's an outline of a way to support adding and removing containers from a running hipache instance.  It isn't implemented yet, but presented here as a discussion topic.  Let me know what you think about the approach, whether this fits in SkyDock proper, whether it should be implemented as a plugin somewhere, or whether I should just keep it in a fork.

The ultimate goal is to allow you to add new containers directly to hipache by simply starting containers.  The container's name will be used as the public URL in hipache.

What about containers we don't want added to hipache?  My url naming convention won't help there.
