Add BucketedTimeSeries to folly

Summary:
Add the BucketedTimeSeries class to folly.  This tracks time series
counter data, using a circular buffer of buckets to expire old data
points as time progresses.

It supports querying the overall sum, count, average, and rate for the
duration of the time series, as well as estimating these values for
portions of the overall duration.

Test Plan: Unit tests included.
