Fix apply of stx-openstack when host is locked
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 and mariadb services cannot use this approach because they are unable to work properly if their replica number is decreased from 2 to 1. So a kubernetes toleration is used here to allow the rabbitmq and mariadb pods to be deployed on the locked controller.
