Async variant of SaveEntity(IEntity2). Saves the passed in entity to the persistent storage. Will not refetch the entity after this save. The entity will stay out-of-sync. If the entity is new, it will be inserted, if the entity is existent, the changed entity fields will be changed in the database. Will do a recursive save. Will pass the concurrency predicate returned by GetConcurrencyPredicate(ConcurrencyPredicateType.Save) as update restriction.
