This MR makes the authentication scope for Pages configurable.
By default, Pages will use api scope to authenticate with Pages Application registered on GitLab.
With this MR, the scope is configurable and can be set to read_api by providing the auth-scope variable within gitlab-pages.conf.
i.e. by adding the following line to gitlab-pages.conf:
auth-scope=read_api
