Multi role RBAC validation

This patchset replaces ``CONF.patrole.rbac_test_role`` with
``CONF.patrole.rbac_test_roles``, where instead of single role
we can specify list of roles to be assigned to test user.

+    We have replaced CONF.patrole.rbac_test_role with
+    CONF.patrole.rbac_test_roles, where instead of single role we can specify
+    list of roles to be assigned to test user. This way we may run rbac tests
+    for scenarios that requires user to have more that a single role.
+deprecations:
+  - |
+    Config parameter CONF.rbac_test_role is deprecated in favor of
+    CONF.rbac_test_roles that implements a list of roles instead of single role.
