Add some more latency-related trace counters
In looking at various RPCs in the new /rpcz profiling mechanism, I noted
that a few sources of latency were not well accounted for. This patch adds
latency counters for the time spent starting new threads (eg if a threadpool
spawns a new worker) and for time spent fsyncing data on disk.
A handy new utility class is used to make this kind of counter easy to add.
