We should add the information when a relay first joined the Tor network
and when it was last seen online. When combined with search parameters, a
community manager person could detect any disappearing or newly joining
relays and contact relay operators.
Step 1 is to add two new fields `first_seen` and `last_seen` to details
files. They would contain the timestamps of the first/last consensus
(bridge status) that contained the relay (bridge). Once we have that, we
can look for relays that have been inactive for up to 7 days (after which
they drop out of Onionoo's data) or for relays that have been first seen
in the past 7 days. Due to the current design of Onionoo's data storage,
a relay that disappears for over a week and returns will have `first_seen`
set to the consensus when it first reappeared.
Step 2 is to extend Onionoo's database to store relays that are inactive
for a longer time, too. We'd have to import all the descriptor archives
to get the `first_seen` field of very old relays right, but that's fine.
Step 3 is to add new parameters `last_seen_days` and `first_seen_days`
which accept a number or a range. If one passes "-7" to `last_seen_days`,
that would means "last seen in last 7 days" which is the current default.
"7" or "7-" could stand for "last seen 7 days ago or longer", "7-14" for
"between 7 and 14 days in the past", etc.
Once we have these fields and parameters, we can extend #6329 or Atlas to
make use of them.
