Rename Metrics/Ooni component to Archived/Ooni
Tickets in the Metrics/Ooni component have been out of scope for Tor metrics people since that component was created, so I'd like to move the subcomponent elsewhere. Turns out that OONI uses their own issue tracker, so they don't need their own top-level component here. But they'd like to have these tickets still available for historical purposes, so they should be in Archived/Ooni.
Making that change in a second, just creating this ticket for documentation purposes.
