Review comment:
No, I take it back. Didn't understand fully your builder until now. We Don't
need this interface and adapter.

> ZOOKEEPER-1416 will add support for Persistent Recursive Watchers. This
> feature allows Curator to re-think/re-write the various cache recipes so that
> they're simpler, use less resources and more stable.
> * Change Curator to depend on ZooKeeper 3.6.x
> * Add a new module so that backward compatibility with 3.5 is ensured
> * Add new methods corresponding to {{ZooKeeper.addWatch()}}
> * Add a new recipe that enables a fully managed Persistent watch
> * Create new Cache recipes that use the new Persistent watch recipe
> * Replace internal usages of TreeCache/PathChildrenCache/NodeCache with new
> cache recipe
> * Deprecate TreeCache/PathChildrenCache/NodeCache
> * Updated docs/tests/etc
