Proxy stats log only what occurred that time interval

Browse source 
Modify the periodic stats output by standalone snowflake proxies to only
include the data transferred during the time interval being logged. This
is an improvement of previous behaviour that logged the total data
transferred by all proxy connections that were closed within the time
interval being logged..
