Revert setting AuthConfig owner reference

[guicassolato]

Merging #303 activated a bug in Authorino that causes it to keep reconciling some AuthConfigs in a loop.

So far, we know that some AuthPolicies (and therefore some AuthConfigs) do not activate the bug, while others do.

Example of AuthPolicy that does not trigger the issue:

apiVersion: kuadrant.io/v1beta2
kind: AuthPolicy
metadata:
  name: toystore
spec:
  targetRef:
    group: gateway.networking.k8s.io
    kind: HTTPRoute
    name: toystore
  rules:
    authentication:
      "api-key-authn":
        apiKey:
          selector: {}
        credentials:
          authorizationHeader:
            prefix: APIKEY
    authorization:
      "only-admins":
        opa:
          rego: |
            groups := split(object.get(input.auth.identity.metadata.annotations, "kuadrant.io/groups", ""), ",")
            allow { groups[_] == "admins" }
        routeSelectors:
        - matches:
          - path:
              type: PathPrefix
              value: "/admin"

Example of AuthPolicy that does triger the issue:

apiVersion: kuadrant.io/v1beta2
kind: AuthPolicy
metadata:
  name: toystore
spec:
  targetRef:
    group: gateway.networking.k8s.io
    kind: HTTPRoute
    name: toystore
  rules:
    metadata:
      foo:
        http:
          contentType: application/x-www-form-urlencoded
          headers:
            Accept:
              value: application/json
          method: GET
          url: http://toystore:3000

This requires investigation.

The PR is just a hotfix while the investigation goes on.
