Restored instance-level support for plain Python descriptors, e.g. ``@property`` objects, in conjunction with association proxies, in that if the proxied object is not within ORM scope at all, it gets classified as "ambiguous" but is proxed directly. For class level access, a basic class level``__get__()`` now returns the :class:`.AmbiguousAssociationProxyInstance` directly, rather than raising its exception, which is the closest approximation to the previous behavior that returned the :class:`.AssociationProxy` itself that's possible. Also improved the stringification of these objects to be more descriptive of current state. Fixes: #4574 Change-Id: I787a22806b5530c146ae6ee66b588e5b191ae689
