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.

Julius Volz 63625bd244 Make view use memory persistence, remove obsolete code. 
This makes the memory persistence the backing store for views and
adjusts the MetricPersistence interface accordingly. It also removes
unused Get* method implementations from the LevelDB persistence so they
don't need to be adapted to the new interface. In the future, we should
rethink these interfaces.

All staleness and interpolation handling is now removed from the storage
layer and will be handled only by the query layer in the future.

Matt T. Proud 13ae29b304 Initial in-memory arena implementation. 
It is unbounded, and nothing uses it except for a gating flag in main.
