It had a max_check_attempts of 1, which makes it susceptible to
network blips.

Jessica McKellar be27ec1ad4 nagios: Change zephyr mirror liveness check to only care about aggregate statistics.
Too many individual users occasionally don't update their mirrors,
causing us to be permanently alerting; we have sufficient user
notification at this point (plus Waseem keeping an eye on /activity)
that we don't need to alert on individual users.

We do, however, still care if something happens (say, Linerva going
down) that causes many users' mirrors to go down.

Keegan McAllister 75526a2c67 nagios: Drop ssh -o StrictHostKeyChecking=no
This is bad for security.

I've checked that all currently known hosts for nagios@nagios.humbughq.com
match one of our existing servers.  When adding servers to nagios in the
future, it will be necessary to do an initial manual ssh from nagios@ and check
the host key fingerprint.
