set X-FORWARDED-* headers for proxied requests

[johann-sonntagbauer]

Description

The local dev server supports a proxy feature. Request will then be routed over a proxy middleware. The proxy middleware should be instructed to send X-FORWARD Header to proper support URL generation on the backend.

Detailed Information why this headers are important can be found here

Expected behavior

The proxy middleware sends the headers.

Actual behavior

No headers will be sent therefor REST Hateoas backend implementations have a hard time to generate links for the client.
