      *Cause*: IPv6 Services were wrongly marked as internal on cloud-provider-openstack.
      *Consequence*: Not possible to share IPv6 load-balancer between OpenShift Services.
      *Fix*: IPv6 Services are not marked as Internal.
      *Result*: IPv6 load-balancers are allowed to be shared between
      Services and the load-balancer can now use a IPv6 stateful address defined in the loadBalancerIP of the Service.

      On ipv6-primary dualstack, it is observed that the test:

      "[sig-installer][Suite:openshift/openstack][lb][Serial] The Openstack platform should re-use an existing UDP Amphora LoadBalancer when new svc is created on Openshift with the proper annotation"

      fails, because CCM is considering it as "internal":

      I0216 10:13:07.053922       1 loadbalancer.go:2113] "EnsureLoadBalancer" cluster="kubernetes" service="e2e-test-openstack-sprfn/udp-lb-shared2-svc"
E0216 10:13:07.124915       1 controller.go:298] error processing service e2e-test-openstack-sprfn/udp-lb-shared2-svc (retrying with exponential backoff): failed to ensure load balancer: internal Service cannot share a load balancer
I0216 10:13:07.125445       1 event.go:307] "Event occurred" object="e2e-test-openstack-sprfn/udp-lb-shared2-svc" fieldPath="" kind="Service" apiVersion="v1" type="Warning" reason="SyncLoadBalancerFailed" message="Error syncing load balancer: failed to ensure load balancer: internal Service cannot share a load balancer"

      However, both LBs do not have the below annotation: 

      "service.beta.kubernetes.io/openstack-internal-load-balancer": "true"
