X-Forwarded-Host for marshalUriFromSapi

[boesing]

Hey guys,

we are using NGINX+ with loadbalancing to multiple servers which are not aware of external domain names (for reasons).
However, NGINX provides X-Forwarded-Host header to those upstream servers to tell them which external domain was called.

I've added an example on what I would like to expect (even tho that X-Forwarded-Proto is being handled for the https scheme).

Tell me what you think.

@boesing it makes sense to me.

here is very old PR to fix it in ZendView helper: https://github.com/zendframework/zendframework/pull/2279/files

I've implemented the way on how that might work.
Just a sidenote: I've skipped that "explode" stuff as per documentation this header only contains a single host (and thats, in fact, is the case for NGINX+ tho).
Probably, the guy who implemented that in zendframework/zendframework#2279 was confused by the X-Forwarded-For header.

Would appreciate some review.
