Lower the log level of a warning for a missing output to debug.
This log line appears repeatedly on successful cluster deletion,
creation failure (for unrelated reasons) and nodegroup creation
failure (again for unrelated reasons, eg timeout). This is
triggered when having multiple magnum conductors all trying to
query the status in heat. Additionally, this warning is not an
indication of a malfunction in a cluster or a failure, so it is
useful only for debugging. Finally, add the cluster id, cluster
status and stack id to have more context.
