STORM-2383 Support HBase as state backend (1.x)
* Implement HBase state backend
* picked Redis state backend implementation
* Current implementation stores prepare/commit/txids into a column family
in a table
* prepare, commit, txids have its row
* they're stored to qualifier:value map (not scalable but guarantee
atomicity)
* we can address atomicity vs scalable later
* Added 'how to set up' to State-checkpointing doc
NOTE: Currently I can't run or debug tests on IntelliJ for master branch
(so worked on 1.x-branch). I also heard many folks are struggling, so might be
better to address it soon.
