Add ability to specify WM(T)S GetMap/GetTile/GetLegendGraphic URL

[marisn]

WMS GetCapabilities response contains URLs based on incoming request. Although it sounds correct, there are scenarios when it is not the case, e.g., Apache internal redirect could mean user must use one URL, but MapCache listens on another URL. Solution would be ability to specify base URL for WM(T)S responses in the configuration file.

Isn't it already there at least for WMS?

wms_onlineresource

WMS TAG Name: OnlineResource (WMS1.1.1, sect. 6.2.2)

Description: (Recommended) The URL that will be used to access this WMS server. This value is used in the GetCapabilities response.

I don't see it in the documentation:

Sorry, I was reading the Mapserver documentation, not Mapcache. I apologize.
