rapid-cdn: Standarize HTTP/2 and other log entries

%HU in case of HTTP/2 results with full URL being logged, while just the path
is expected in the log.

Even if the change comes from http://git.haproxy.org/?p=haproxy.git;a=commit;h=30ee1efe676e8264af16bab833c621d60a72a4d7
it has been detected since full HTTP/2 aware test client has been used.
