+    Add new exception called ``RbacOverrideRoleException``. Used for
+    safeguarding against false positives that might occur when the expected
+    exception isn't raised inside the ``override_role`` context. Specifically,
+    when:

+    * ``override_role`` isn't called

+    * an exception is raised after ``override_role`` context

+    Previously, the ``rbac_rule_validation.action`` decorator could catch
+    expected exceptions with no regard to where the error happened. Such
+    behavior could cause false-positive results. To prevent this from
+    happening from now on, if an exception happens outside of the
+    ``override_role`` context, it will cause
+    ``rbac_exceptions.RbacOverrideRoleException`` to be raised.

+    In order to implement the tests for plugins which do not maintain the

+      config option. Using ``glob.glob()`` function makes it possible to use

+
+    - Loading and merging a data from multiple policy files.
+      Patrole loads a data from each of the discovered policy files for a
+      service and merge the data from all files.
