[DISCUSS] Merge FilterList Improvement - Branch HBASE-18410

[OpenInx]

Hi All :


All subtasks have been resolved except HBASE-18993
<https://issues.apache.org/jira/browse/HBASE-18993>, I think it's time to
merge HBASE-18410 <https://issues.apache.org/jira/browse/HBASE-18410> branch
to master now.

Any concerns ?

Thanks.
