Looks good!
I would suggest two followups:
1. We can probably drop `flink-shaded-curator` as well, because curator
shaded guava by itself in the currently used version (still needs an exclusion
because they do not build the dependency reduced pom).
2. Add a `ZooKeeperAccess` util in `flink-runtime` for the access to
ZooKeeper done in `flink-mesos`. That way, `flink-mesos` needs no direct ZK
dependency.---
