Add reseek optimization for fetching multiple versions via TimestampsFilter
---------------------------------------------------------------------------

                 Key: HBASE-3005
                 URL: https://issues.apache.org/jira/browse/HBASE-3005
             Project: HBase
          Issue Type: Improvement
          Components: filters
            Reporter: Pranav Khaitan
            Assignee: Pranav Khaitan


Skip between timestamps to avoid the unnecessary read for all the blocks which come in between.

For example:

If we have timestamps from 1 to 1000 for a particular row, family, qualifier and we want to
read only timestamps 990 and 10, then we should be able to read 990 and then jump to 10 instead
of doing a sequential read including everything in between.
