Description

This initial patch has several important features:

1. HBaseStore, a new implementation of RawStore that stores the data in HBase.
2. Subclasses of the thrift metastore objects to remove the massive duplication of data where every partition contains a nearly identical storage descriptor.
3. Caches for catalog objects and statistics so that repeated metastore calls don't result in repeated calls against HBase.

Currently this "works" to the point that "load table" and "select" work. I have not tested any other statements, and I suspect most fail. There is no security, no authorization, and a no a lot of other things.
