Is your feature request related to a problem? Please describe.

Gloo requires a prefix matcher on a VS route delegateAction which limits our ability to delegate routes to RTs. We would like to be able to delegate to RTs using regex or headers matchers. If you configure a delegateAction with a regex, for example, you get this:

invalid route: routes with delegate actions must use a prefix matcher

    routes:
    - delegateAction:
        name: regex
        namespace: gloo-system
      matchers:
      - regex: /foo/(bar/|(xyz/1[.]0))

Describe the solution you'd like

Support all matcher types for delegateAction

Describe alternatives you've considered

Don't delegate non-prefix matchers to RTs

is it too constrained if the parent cannot use regex? or if the parent regex must match identically?
