Changing instance from a subclass of Compute instance into its own object.

* Attaching properties such as the current task and service status.
* Added a TaskStatus class to store enumeration style values for status.
* Brought in GuestStatus class from RD Legacy, renamed it ServiceStatus.
* Moved function to create Nova client into a module.
* Added some properties to instance to reflect compute instance fields we wish to forward.
* Fixed pep8 and unit tests.
