Ú_ContextAuthPluginzñA keystoneauth auth plugin that uses the values from the Context.
Ideally we would use the plugin provided by auth_token middleware however
this plugin isn't serialized yet so we construct one from the serialized
auth data.

:param action: string representing the action to be checked.
:param target: dictionary representing the object of the action
for object creation this should be a dictionary representing the
location of the object e.g. ``{'project_id': context.project_id}``.
If None, then this default target will be considered:
{'project_id': self.project_id, 'user_id': self.user_id}
:param fatal: if False, will return False when an exception.Forbidden
occurs.
:raises dmapi.exception.Forbidden: if verification fails and fatal is
True.
:return: returns a non-False value (not necessarily "True") if
authorized and False if not authorized and fatal is False.
