BREAKING: changes to CLI interface, moved to cobra CLI

To better support configuration and user friendliness, migrated to cobra based CLI.  The source tree structure has also changed to single go module, the server has been renamed hypd and client has been named hyp.  The original structure came into being organically, but now that the vision is more complete it's best to make these adjustments now.
