Begin removal of FTP mirror support

FTP is a terrible protocol these days compared to HTTP. IPv6 support is
spotty at best, it is much slower for the connect/begin transfer cycle,
and overall just doesn't provide anything HTTP does better. Start
killing bits that we've added to treat FTP as a first-class protocol and
regulate it to the back seat.

The expectation here is once this commit goes live to the production
site, the FTP mirror URLs themselves will get removed completely from
the database, and the FTP protocol object itself will get deleted.
