Add Knative metrics to Prometheus

See merge request gitlab-org/gitlab-ce!23972

GitLab 11.6.2 fixed the case for HTTP. However, HTTPS still did
not work because the protocol returned to `http_enabled?`
was the actual protocol in use (e.g. `https` instead of `http`).

Add rel=me to user's website link

See merge request gitlab-org/gitlab-ce!24089

rel=me links allow cross-linking of user's identities. This behavior is
used by software to determine if user controls profiles on two different
sites. For example Mastodon uses it to display verified badge on links.

Both Twitter and GitHub automatically add rel=me to links added to
users' profiles.
