Matt T. Proud 161c8fbf9b Include deletion processor for long-tail values. 
This commit extracts the model.Values truncation behavior into the actual
tiered storage, which uses it and behaves in a peculiar way—notably the
retention of previous elements if the chunk were to ever go empty.  This is
done to enable interpolation between sparse sample values in the evaluation
cycle.  Nothing necessarily new here—just an extraction.

Now, the model.Values TruncateBefore functionality would do what a user
would expect without any surprises, which is required for the
DeletionProcessor, which may decide to split a large chunk in two if it
determines that the chunk contains the cut-off time.

Matt T. Proud ce45787dbf Storage interface to TieredStorage. 
This commit drops the Storage interface and just replaces it with a
publicized TieredStorage type.  Storage had been anticipated to be
used as a wrapper for testability but just was not used due to
practicality.  Merely overengineered.  My bad.  Anyway, we will
eventually instantiate the TieredStorage dependencies in main.go and
pass them in for more intelligent lifecycle management.

These changes will pave the way for managing the curators without
Law of Demeter violations.
