The spec defines a single core trait ManualScaler, but seems to be missing additional core traits that are implemented by Rudr:
https://github.com/oam-dev/spec/blob/master/5.traits.md#core-traits

Rudr implements the following additional traits that are not defined in the spec:

• ingress.core.oam.dev/v1alpha1
• auto-scaler.core.oam.dev/v1alpha1
• volume-mounter.core.oam.dev/v1alpha1

Since nteract/vdom#14, we've started generating documentation on the fly for the component helpers. We could take this another step if we want, changing createComponent like this:
