Add samples for AppConfig LRO CreateSnapshot with comparisons of what we'd expect the user experience to be. (#6345)
* Add samples for AppConfig LRO CreateSnapshot with comparisons of what we'd expect the user experience to be.

* Add the necessary thread include.

* Update LRO sample where Operation<T> returns a status monitor instead of the resource.

* Add initial result to get the snapshot back from the first request, and fix formatting.

* Update the return type of GetSnapshot to match existing, current API shape.
