    Refactor Keystone client with keystoneauth

    This patch does, basically, three things:

    * Updates the default auth section to keystone_auth;
    * Introduces keystoneauth sessions and plugins;
    * Adds a deprecation warning and options when loading
    legacy auth.

    Config, tests and client code are also updated.
