[ntp] Log distribution of NTP loads
This CL adds a histogram, which logs, when an NTP loads, the time since
the previous NTP started loading. This should give us the distribution
of how frequently NTPs load.
The hope is that this metric allows us to better judge what caching
strategies should be employed to reduce server requests made by NTP
modules.
