[schema/security] add __hash__ to rql expression. Closes #3013535
This is required so that when some rql expression participate to a dictionary
key, only the expression is considered (consistent with comparison). This
behaviour is expected in security at least, see the related bug for instance.
This scramble msplanner unit tests a bit.
