d9f8a0920c Move StatsBuffer to be time-based. 
It now keeps stats for a certain amount of time before expiring them. It
used to keep a certain number of stats instead.

38203d1d49 Break storage/memory from the StorageDriver API. 
It is not a StorageDriver, rather it is the always-existing memory
storage.

3b6ac51f6f Add InTimeRange() to StatsBuffer. 
This will allow us to accept queries over a narrower window of time.

9b5b221a57 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.

10d631be6d Factor out data comparator for storage tests. 
For influxdb, we are planning to export lesser data. Having a separate
comparator will let us reuse the same tests.
