perf(stats): read peers from instances, update every 5 minutes

Browse source 
The peers query read the nickname of every remote user every minute
(2.7 s and 1.2M buffer hits on a large instance). The instances table
now has a row for every host we know users from, so read it instead,
and recompute the stats every 5 minutes.

Based on Akkoma 138b1aea2 and 7b76fdeed.
