Ability to filter routes by COPY http method

[jm890]

What would you like to be added:
I'm evaluating a migration away from nginx-ingress, and noticed COPY is not a valid method inside an HTTPRoute rule.
I'd like to be able to specify this method inside of a route rule.

matches:
- path:
    type: PathPrefix
    value: /
  method: COPY

Why this is needed:
We use a couple of services that make use of this method.
