Here's what I came up with. I think this should replace both
jk/http-backend-handle-proto-header and kr/doc-webserver-config-for-v2.
The latter does give some specific nginx tips which I didn't carry over,
but they shouldn't be necessary after the change in http-backend. If we
do want to include them, they can be mentioned as optional if we later
add an nginx example config to the http-backend manpage.
