Currently, all of the stx-openstack services have the replica count set to the number of the controllers. If one of the controllers is locked their replicas number will still be 2 which is incorrect. We solve this by changing the number of replicas to be equal to the number of the active controllers. The rabbitmq service cannot use this approach because it is unable to work properly if its replicas number is decreasaed from 2 to 1. So a kubernetes toleration is used here to allow the second rabbitmq pod to be deployed on the locked controller.
