Branch off of master for HDFS space quota work? (HBASE-16961)

[Josh Elser]

Hi folks,

I've gotten far enough along that I have some confidence in what I 
worked on early on in the feature is actually sensible. As such, I'd 
like to start working through the review process of each incremental bit 
of work (the child issues).

As each child issue is reviewed, it would be nice to land it somewhere. 
Any opinions on setting up a feature branch for this? Still the desired 
approach? Asking for branch committer privileges could also be a 
follow-on question (assuming the feature-branch is agreed upon) to avoid 
more work on you fine people ;)
