nova-scheduler errors out if placement service is not available even if the container healthchecks shows active. Add placement integration in nova-k8s to ensure placement is defined in the bundle/tf plan Add ServiceReadinessProviderHandler in placement-k8s and corresponding RequiresHandler in nova-k8s. Fixes: #2097327 Change-Id: Ica072b98c4668c6248702ca680b2885c4d542e23

juju relate mysql:database nova:cell-database
juju relate rabbitmq:amqp nova:amqp
juju relate keystone:identity-service nova:identity-service
