CURATOR-470
Introduces an alternate cache listener, ServiceCacheEventListener, that
gives more detail about changes to the cache as opposed to the original version
which merely denotes a change.

> Affects Versions: 4.0.1
> Reporter: Jerry Chin
> Priority: Major
>
> Hey fellows,
> We're using _service discovery_ extension to refactor our raw zookeeper based
> service monitor.
> Every time a service instance exits or joins, the monitor must be notified
> and push a notification to us, the only thing I found in _service discovery_
> package meets the requirement is {{ServiceCacheListener}} interface, but when
> the interface is fired, there's no way we could know which service has
> changed.
> Please help !
> Thank in advance.
