[skmo] Add Skupper for cross-region RabbitMQ and Keystone internal routing

Add hook playbooks and configuration to establish Skupper virtual
services for RabbitMQ and Keystone internal endpoints, enabling
cross-region connectivity in the multi-namespace SKMO scenario.

skupper-connector.yaml: query the RabbitMQ TLS secret from the correct
CRD - rabbitmq.openstack.org/v1beta1 (RabbitMq) as used by the
OpenStack infra-operator, not the community rabbitmq.com/v1beta1
(RabbitmqCluster). Add retries to wait for spec.tls.secretName to
be populated before creating the Skupper Connector.

skupper-keystone-connector.yaml: add retries to the KeystoneAPI CR
lookup to wait for spec.tls.api.internal.secretName to be available,
since that field is not populated until Keystone completes TLS setup.

configure-leaf-keystone-internal.yaml: after patching the leaf OSCP
to use the Skupper Keystone virtual service, also create a MetalLB
LoadBalancer Service (keystone-regionone-lb) and a DNSData CR
(keystone-skupper) so that EDPM compute nodes outside the OCP cluster
can resolve and connect to the Keystone auth_url. The Skupper Listener
creates a ClusterIP-only Service that is unreachable from EDPM nodes;
the LoadBalancer Service obtains a MetalLB IP on the leaf internalapi
network and the DNSData entry registers both the short (.svc) and
fully-qualified (.svc.cluster.local) names in the dnsmasq instance
serving those nodes.
