[merlimat]

Motivation

Recently merged improvements in BookKeeper OrderedExecutor (see apache/bookkeeper#1309 ). We need to update Pulsar code with the refactored names.

I guess we will always run into these issues as long as we keep pointing to SNAPSHOT jar.

Maybe we should eventually stop using BK SNAPSHOT jar.

Yes, once we're sure BK 4.7 is ready and has all the pieces we need for Pulsar, a release will be made and we'll switch to that release. That should happen soon.

There were a lot of thing that we had to adjust on both Pulsar and BK side to make the transition to 4.7, it wasn't just possible to make these changes in a branch and sync with master.
