[VOTE] Release ZooKeeper 3.1.0 (candidate 0)

[Patrick Hunt]

I've created a candidate build for ZooKeeper 3.1.0. Over 65 JIRAs are 
addressed in this release, with major new features for Quota, JMX, and 
Bookkeeper (transactional log store) to name a few. Full details in the 
release notes.

Should we release this?
