Eric Fried 061cc67c3b Nix unused raise_if_custom_resource_class_pre_v1_1
The only reference to
nova.db.sqlalchemy.resource_class_cache.raise_if_custom_resource_class_pre_v1_1
was removed in Ideca0f09f5dc4ba6bb194a2413ed93cf592dd963.  This was also the
only place nova.rc_fields.ResourceClass.V1_0 was used.  This patch removes
both.
