Title: Buffer stats in influxdb driver before writing to the Db. 

The buffering duration is configurable via a flag and is set to 60 seconds by default.
This new flag replaces exiting flag "history_duration" since they both are inter-dependent.
The storage driver test code has been re-factored a bit to help test the new buffering
feature and will be future proof.
