Hey!

Tried to use reproxy for the first time and got some issues with services like Grafana.
It looks like Grafana server doesn't handle X-Forwarded-Host header which is non-standard. But there is no ability in reproxy to bypass Host header like you can do with nginx:

proxy_set_header Host $host;

It may be implemented using command line flag or we can enable it by default.
What do you think about it?

Thanks!
