This new reliance on buildfarm.postgresql.org/branches_of_interest.json is
trouble for non-SSL buildfarm animals.
http://buildfarm.postgresql.org/branches_of_interest.txt has an exemption to
allow serving over plain http, but the json URL just redirects the client to
https.  Can the json file get the same exemption-from-redirect that the txt
file has?
