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.
The storage driver test code has been refactored a bit to help test the new buffering
feature and will be future proof.

Remove page faults from cadvisor UI.
Page fault data is useful for inference and performance detection, but
it doesn't make sense on the summary UI. We have limited space on the
main container page. Let's use it for main throughput signals. Removing
faults make network stats more prominent too.
