Support hybrids/composites with bulk updates
The :meth:`.Query.update` method can now accommodate both
hybrid attributes as well as composite attributes as a source
of the key to be placed in the SET clause. For hybrids, an
additional decorator :meth:`.hybrid_property.update_expression`
is supplied for which the user supplies a tuple-returning function.
