#8151: Dirauths should publicize their flag cutoff values in their votes

----------------------+-----------------------------------------------------
To detect sybil attacks faster, it might be a good idea for dirauths to
publicize their flag cutoff values in their votes.
This way they can be collected and analyzed, and maybe used by a script
like consensus-health to detect anomalies.
(For example, in yesterday's attack, the cutoffs of moria looked like:
{{{
Cutoffs: For Stable, 404881 sec uptime, 242577 sec MTBF. For Fast: 1
bytes/sec. For Guard: WFU 95.962%, time-known 110475 sec, and bandwidth
71680 or 58291 bytes/sec. We have enough stability data.
}}}
(see the `Fast` cutoff))
