 Just like we write 'unparseable-desc' and 'v3-status-votes' to a file, it
 would be great to write 'unpublished[-flavour]-consensus' to a file, when
 we log this message:

 {{{
 Nov 10 21:00:01.000 [warn] A consensus needs 5 good signatures from
 recognized authorities for us to accept it. This one has 4 (...). 4 (...)
 of the authorities we know didn't sign it.
 Nov 10 21:00:01.000 [warn] Not enough info to publish pending ns consensus
 }}}

 Similarly, when we disagree about signatures, we should write
 'unpublished-[-flavour]-signatures', when we log this message:
 {{{
 Nov 10 21:27:32.000 [warn] Problem adding detached signatures from
 <redacted-address-and-port>: Mismatched digest.
 }}}
 (Or, even better, write both matching and mismatching signatures to the
 file.)

 One catch:
 These new filenames need to be added to the sandbox.
