Comment:

 Following the proposed KeyValues in https://pad.riseup.net/p/sbws-exclude-
 reasons-keep:
 - any KeyValue that is based on the last bandwidth file adds more code
 complexity, because it would mean to read and parse the last bandwidth
 file
 - fetch consensus every hour (instead of every 5min) so that we can assume
 every consensus fetched is new
 - store the number of times a relay is in the consensus
 - created a KeyValue to report the number of time a reported relay was in
 the consensus
 - a header KeyValue with the total number of consensus could be calculated
 as the the maximum number of consensuses in a bandwidth line (maybe
 missing some?)
 - it can't be know the relays that were not in any consensus, since they
 won't be reported
 - it'd be possible to report the number relays that were not in any
 consensus
