* Renamed the auth_type "basic" to the more apt "auth1.1".
* Made it possible to pass an "token" and "service_url" argument alone to
  the client. It wouldn't work with just this before.
* The client now saves all arguments you give it to the pickled file,
  including the auth strategy, and preserves the token and service_url
  (which it didn't before) which makes exotic auth types such as "fake"
  easier to work with.
* Not raising an error for a lack of an auth_url until auth occurs
  (which is usually right after creation of the client anyway for most
   auth types).
* Moved oparser code into CliOption class. This is where the options live
  plus is the name of that pickled file that gets stored on login.
* Added a "debug" option which avoids swallowing stack traces if
  something goes wrong with the CLI. Should make client work much easier.
* Added a "verbose" option which changes the output to instead show the
  simulated CURL statement plus the request and response headers and
  bodies, which is useful because I...
* Added an "xml" option which does all the communication in XML.
* Fixed a bug which was affecting the CI tests where the client would fail
  if the response body could not be parsed.
* Added all of Ed's work to update the mgmt CLI module with his newer
  named parameters.

- Added parameters for the authentication instead of the arguments.
- Cleaned out the HttpClient and Authentication pieces.

* Nova client changed in a way that broke our client, so copying the code from there is necessary.
* Adding InstanceStatus class with the status strings.
* Moved the Dbaas and ReddwarfHTTPClient into their own module.
* Changed exceptions module to check Nova's exception map after first looking in Reddwarf's.
