work that is going on HBase-4676.

> Right now, a millisecond-level timestamp is attached to every record. 
> In our case, we only need a version number (mostly it will be just zero etc). A millisecond
timestamp is too heavy to carry. We should add support to overwrite it to zero during major
compaction. 
> KVs before major compaction will remain using system timestamp. And this should be configurable,
so that we should not mess up if the hbase timestamp is specified by application.
