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 38d839d810 Include generated Protocol Buffers artifacts.
This commit reduces the general compile time dependencies to omit
the Protocol Buffer compiler and the Go Protocol Buffer generator
tool.  The build steps to furnish them still remain, but they can
optionally be called if data.proto or config.proto are under work.
