(Ashutosh Chauhan via Carl Steinbach)

Summary:

This patch adds support for key range scans pushdown to hbase for keys of type
string. With this patch filter pushdowns of following types are supported:
a) Point lookups for keys of any types.
b) Range scans for keys of type string. 

Test Plan:
Added hbase_ppd_key_range.q which is modeled after hbase_pushdown.q

This is a subtask of HIVE-1643

> HIVE-1226 added support for WHERE rowkey=3.  We would like to support WHERE rowkey BETWEEN 10 and 20, as well as predicates on non-rowkeys (plus conjunctions etc).  Non-rowkey conditions can't be used to filter out entire ranges, but they can be used to push the per-row filter processing as far down as possible.
