Peter Portante d4e02a2e8b Add accurate timestamps in proxy log 
Add accurate timestamps to the proxy-logging middleware log lines for
the start and end of a request. We use 9 digits of precision since on
some systems the clock resolution can be as fine as 1 ns.

The goal is to allow for log processing that can use the more accurate
timestamps to correlate requests, computing number of requests in
flight at a given historical point in time.
