Summary
-------

Support alternate compression for major compactions.

This is expected to be an uncommmon configuration so I did not pollute the HColumnDescriptor constructor with the new option; instead only added convenience {get,set}ters.


This addresses bug HBASE-2988.

Testing
-------

Created table with LZO compression, inserted 10GB of data, altered schema with COMPRESSION_COMPACT of 'LZMA' (custom LZMA Hadoop compression plugin), initiated major compaction, confirmed the results by examining HFiles on local fs with the UNIX file utility.


Thanks,

Andrew
