CI: Stop using infra cache servers as registry

We are seeing frequent CI job failures due to timeouts while fetching
container images. See similar change in kolla-ansible [1].

Also remove the kolla_docker_namespace variable from CI overrides:
"openstack.kolla" has been the default value since 2021 [2].
