Allow searching for relays with no known AS/country
Currently it is not possible to drill down on the aggregated view in relay search into the "Unknown" AS or country.
Relay Search uses xz as the unknown country code, and AS0 as the unknown autonomous system.
It would not be needed to return these in the details documents, but only to build indexes with these values.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
