Add support for custom domains to the Pages internal API
What does this MR do?
This is another extraction from https://gitlab.com/gitlab-org/gitlab-ce/issues/61927 in order break the later in smaller chunks.
This MR add support for custom pages domains to the endpoint introduced in https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/32732. Namespaces domains are intentionally left out cause this is where the data migration and tricky queries will happen, this way we can introduce most of the code we'll eventually need before we add the last piece.
Keep in mind this branch is based on https://gitlab.com/gitlab-org/gitlab-ce/tree/61927-skeleton-pages-internal-api and can be merged only once https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/32732 is merged.
