Apart from making keystoneclient follow the same patterns of using an
adapter that we are trying to push onto other clients this severs the
cyclical dependency between managers and the client object.

There are a few changes that have had to be rolled into one to make the
transition work. These can't be separated unfortunately as they are
interdependent.

* managers are now passed the adapter instead of the client. They
  therefore don't have reference to the other managers on the client.
* The adapter has been subclassed to provide user_id as there are some
  managers that require user_id be provided for changing passwords etc.
* client.auth_url has been replaced with a call to get_endpoint which is
  supported by the adapter.
* management=True has been removed from all the managers and they now
  correctly set the interface they want.
