    Create OpenStackClients convenience class

    The OpenStackClients class provides a convenient way to create and
    cache client instances. The idea behind this code comes from Magnum
    [0].

    The OpenStackClients class will act as the manager of other project's
    clients, providing an easy way to fetch instances of said clients. This
    will allow the clients to be cached.

    An instance of OpenStackClients is created for every call that comes
    into the decision engine and the applier, using the request context to
    pass needed (domain id) parameters to get a Keystone session. This
    instance should be shared as much as possible to avoid additional
    unneccessary connections to the other services.

    This class will also allow for the version of each client to be
    configurable via the watcher.conf file.

    The method by which a Keystone session is also changed to use the
    keystoneauth1.loading library. In order to avoid DuplicateOptErrors
    with the keystone_authtoken group used for the keystonemiddleware in the
    API code, a new conf group named "watcher_clients_auth" is created. A
    typical configuration using a password authentication scheme will look
    like:
      [watcher_clients_auth]
      auth_type = password
      auth_url = http://<server-ip>:<port>
      username = <username>
      password = <password>
      project_domain_id = default
      user_domain_id = default
