Add a new Filter that checks a single column value but does not emit it.
------------------------------------------------------------------------

                 Key: HBASE-2211
                 URL: https://issues.apache.org/jira/browse/HBASE-2211
             Project: Hadoop HBase
          Issue Type: New Feature
    Affects Versions: 0.20.3
            Reporter: Ferdy
         Attachments: HBASE-2211.patch

Performance wise, it may be necessary for a filter to test a column for a specific value (like
SingleColumnValueFilter) , but exclude the KeyValue from the output. This is certainly the
case when the column values are large in size.

In order to keep SingleColumnValueFilter simple and maintainable, I decided to subclass it.
SingleColumnValueExcludeFilter is the result. Tests are included.
