New feature or improvement

You can use the following annotations to control the redirect behavior.

• k8s.apisix.apache.org/http-to-https

If this annotation set to true and the request is HTTP, it will be automatically redirected to HTTPS with 301 response code, and the URI will keep the same as client request.
