+1 for the change, but only applying to 1.x version line. (-1 for merging
in master branch)
We're changing backpressure model in
[STORM-2306](https://issues.apache.org/jira/browse/STORM-2306) which got remove
of usage of ZK for backpressure, and I think the PR is getting closer to the
finish line (target to be included to Storm 2.0.0), hence I don't want to make
things conflict.---
