NGINX - Custom Parameters.

[itngo]

Currently we create include files to workaround some issues.
Example Safari on MacOS does not like UPGRADE-Header in http/2 and refuses to load webpage.
Instead of searching for the right file-name for the location-include, it would be nice if that file gets auto-created and maybe have a text-field in WebGUI where these parameters can be put.

Making this for 200 Webs and Locations is a bit hard at least else....
