support custom request header

[shuaiyy]

Describe the solution you'd like

I need to add a cookie value to http header, just like the nginx ingress controller

nginx.ingress.kubernetes.io/configuration-snippet: "proxy_set_header X-User-Id $cookie__id;"

@shuaiyy, ALB doesn't support adding custom request headers at the moment. Feature request #1571 to keep track of the issue.

[kishorj]

Closing the issue since we are already tracking the feature request.
