If the collection info contains a embedded document called "view" then it should only create the "view" collection, but not load any data nor create/build indexes.
This should be done:
- Where we call getCollectionInfos in Cloner::copyCollection/copyDb
- Where collections info create a new CollectionCloner. We can either specialize a subclass to clone views (read-only collections) or handle it in CollectionCloner.
