Preserve X-Forwarded-Host in Ingress

[shaun-nx]

Is your feature request related to a problem? Please describe.
If I have an Ingress Resource deployed, and I send a request with X-Forwarded-Host header, the value in the header is not preserved

Describe the solution you'd like
The command below should return ‘bogus.example.com’:

$ curl --header "X-Forwarded-Host: bogus.example.com"  https://www.example.com
            "x-forwarded-host": "bogus.example.com",
            "host": "www.example.com"

Instead, it returns ‘www.example.com’ for both ‘x-forwarded-host’ and ‘Host’:

$ curl --header "X-Forwarded-Host: bogus.example.com"  https://www.example.com
            "x-forwarded-host": "www.example.com",
            "host": www.example.com

Describe alternatives you've considered
We would have to create a custom annotation, which is less than desirable
