Add knative prefix back to the annotation key

[benjaminhuo]

Description
Currently, openfunction support adding knative annotations but without knative prefix

We should support the original annotation key style with knative prefix like autoscaling.knative.dev/min-scale: "3"

Additional context

Is this method available in version 0.7.0

@wrongerror We need to make changes to the knative params as we've discussed before in v0.8.0
