pgbench: Elaborate latency reporting.
Isolate transaction latency (elapsed time between submitting first
command and receiving response to last command) from client-side delays
pertaining to the --rate schedule. Under --rate, report schedule lag as
defined in the documentation. Report latency standard deviation
whenever we collect the measurements to do so. All of these changes
affect --progress messages and the final report.
