Deprecate Pages daemon-* flags
We have now disabled chroot by default since %14.1, and recently removed support for disk-based configuration coming in %14.3. And we've also removed the chroot completely from Pages.
However, we still support daemonizing and in fact Omnibus still configures Pages to run as daemon https://gitlab.com/gitlab-org/omnibus-gitlab/-/blob/5b4022e03873d3b38b466b17b633812b175fc0fe/files/gitlab-cookbooks/gitlab-pages/templates/default/gitlab-pages-config.erb#L4.
We should deprecate the following flags:
daemon-uid
daemon-gid
daemon-inplace-chroot
And give way to gitlab-pages#133 (closed)
