Added general class for testing keystone audit middleware
functionality in charms. Tests correct rendering of
api-paste.ini file and allows charms without an api-paste.ini
file to skip the tests.
Example usage with charm Heat:
tests/tests.yaml
tests:
- zaza.openstack.charm_tests.audit.tests.KeystoneAuditMiddlewareTest
tests_options:
audit-middleware:
service: heat
