[CURATOR-332] Internal watcher tracking for new
WatcherRemoveCuratorFramework feature is not correct
Reworked WatcherRemovalManager. It now stores watchers only on successful
operations. This is more like how ZK does it.
Also, exists watcher must be stored when there is a NoNode result.

> Project: Apache Curator
> Issue Type: Bug
> Components: Framework, Recipes
> Affects Versions: 3.1.0
> Reporter: Jordan Zimmerman
> Assignee: Jordan Zimmerman
> Fix For: 3.2.0
>
>
> The WatcherRemoveCuratorFramework introduced in 3.0.0 doesn't track watchers
> correctly and can sometimes lose track of some watchers and, thus, not delete
> them when requested to. Examples:
> * Exists watchers stay set even when there is a NoNode exception
> * If a watcher is successfully set and then the same watcher is used during a
> network failure, WatcherRemoveCuratorFramework will clear the watcher
> internally.
