puppet: Run check_ntp_time against an NTP pool instead of time.mit.edu
...
MIT implemented NTP rate-limiting to defend against on-going reflection attacks,
which was causing our nagios checks to fail intermittently. When the attacks
die down or when external sites fix their NTP configurations, checking against
time.mit.edu will stop failing. However, there also isn't much of a reason to
stick with checking against a single server.
