Improve StackValidationFailed response in properties

In some cases, there is no information about resource and
section, where Property error raised. This patch improves
StackValidationFailed msg, so this msg look like "Property
error : resource_name.section_name.key_name: error_msg", where
section_name is section, where Property error raised, e.g.
'update_policy'.
