Comment (by teor):

 Note for the review assigner:

 ahf wants to review tor bandwidth authority patches.

 Note for the reviewer:

 Let's get a simple version of this patch working first. The simplest
 version sends the bandwidth file that is on disk right now.

 Then we can follow up with:
 * #27047: authorities should keep recent consensuses, votes, and bandwidth
 files
 * #26797: read the file once per vote, and use the cached file for votes
 and bandwidth file requests
 * #26698: put a hash of the bandwidth file in the vote
