Fix tls field in watcher kuttl test suite

The kuttl test suite had a misplaced caBundleSecretName field. This was
not detected before because even though the pods could not communicated
properly with keystone or rabbitmq, they kept running. After switching
to containers built from watcher master, the decision engine tries to
connect to keystone and fails, crashing.
