Access controls for Pages on gitlab.com

Problem to solve

The ability to set up access control for pages was introduced in https://gitlab.com/gitlab-org/gitlab-ce/issues/33422.

There is now an infrastructure ticket to enable it in production: https://gitlab.com/gitlab-com/gl-infra/infrastructure/issues/5576. This issue represents the engineering team's work to work with the infrastructure team to ensure that happens.

• check what happens when you disable access control(@vshushlin: 404 for me locally, which is strange)

Further details

This is a great, working feature that would be valuable to users on gitlab.com as well. We need to ensure that the solution will work and be performant/not cause other issues on gitlab.com before enabling it.

Proposal

Complete infrastructure ticket and enable feature on gitlab.com.
