What this PR does / why we need it:

Allows users to use the header manipulation feature of response-rewrite plugin in APISIX via annotations in Ingress resource. Solves #1860

Example
Case 1: Remove Server header

# use v1beta1 if your Kubernetes cluster version is older than v1.19.0
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: httpserver-ingress
  annotations:
    k8s.apisix.apache.org/response-rewrite-remove-header: "Server"
    k8s.apisix.apache.org/enable-response-rewrite: "true"
spec:
  # we use APISIX Ingress and it watches Ingress resources with "apisix" ingressClassName
  ingressClassName: apisix
  rules:
  - host: mockbin.org
    http:
      paths:
      - backend:
          service:
            name: httpbin

            port:
              number: 80
        path: / 
        pathType: Prefix

No server header in response
