Add geo-awareness into Availability API requests

[mekarpeles]

Proposal

Requests from Open Library (already attaching x-preferred-client-ip headers) will need to include x-preferred-client-useragent and x-preferred-client-jurisdiction (two-character geoip location country code) along with the request.

This issue can be resolved once:

• Open Library updated nginx to deduce the jurisdiction from an IP at nginx level, related to Switch nginx to use njs for IP anonymization #10139
• core.lending code passes this jurisdiction along to the bulk availability service https://github.com/internetarchive/openlibrary/blob/master/openlibrary/core/lending.py#L378-L400
• @ximm and @mekarpeles coordinate to update the bulk availability API to pass along jurisdiction to ES

Justification

Access to some items within the Internet Archive's purview are geographically restricted.

Currently, this only affects a few hundred Open Library records:
