Review request for hbase, Dhruba Borthakur, Michael Stack, and Li Pi.


Changes
-------

Diff attached now.


Summary
-------

Creates a new CacheConfig class and moves almost everything block cache related into this
single class.  Adding new configuration params and booleans and such should be much better.

All tests are NOT passing yet, still working on it, but wanted to have something up today.
 Basically "code complete" but broken :)


This addresses bug HBASE-4422.

> From StoreFile down to HFile, we currently use a boolean argument for each of the various
block cache configuration parameters that exist.  The number of parameters is going to continue
to increase as we look at compressed cache, delta encoding, and more specific L1/L2 configuration.
 Every new config currently requires changing many constructors because it introduces a new
boolean.
> We should move everything into a single class so that modifications are much less disruptive.
