Add a StatisticsDeltaReader class and use cases
This CL adds a utility class to streamline the task of testing that
metrics have been updated as expected. Specifically, the
StatisticsDeltaReader class allows a client to obtain the differential
value of a given histogram in the interval since the given
StatisticsDeltaReader instance was created.
This reverts commit 6a7dfb3cd638829a04e002ea9bc5b18ed3c9c03f.
