Should be able to update Pages Domain Certificates
Currently, you can only add or delete a custom domain under Pages. This means that in order to add or update a certificate for the domain, you must first delete the domain, then add it back in. This is a very messy process that means there would be a window of time when the custom domain was not recognized by gitlabs.io as legitimate and return a 404.
Please add the ability to add/update certificates for domains after the domain has been created.
