Improve ProxyHeadersMiddleware (#​2468) and (#​2231):

• Fix the host for requests from clients running on the proxy server itself.
• Fallback to host that was already set for empty x-forwarded-for headers.
• Also allow specifying IP Networks as trusted hosts. This greatly simplifies deployments
  on docker swarm/Kubernetes, where the reverse proxy might have a dynamic IP.
  • This includes support for IPv6 Address/Networks.
