Gitlab Pages Support

Gitlab-pages image is going through registry1 pipelines and once complete add the image and other necessary configuration to the package to get it running but keep pages disabled by default.

pages expects a wildcard endpoint and certificate so we will have to adjust the existing, or add a new VirtualService to support the routing to be able to reach pages at *.domain (or maybe only a subdomain will work).

• Pages specific overrides and registry1 image
• VirtualService and other istio routing additions to support pages installation
