Add preserveHeaderCase argument (dart-lang/http_multi_server#22)

An upcoming SDK release will add a named argument which must be included
for any class which `implements` the interface. Pre-emptively add the
argument to the signature so that we have a version of this package
which is forward compatible with the SDK. We will properly forward the
argument once we have an SDK release with the change.
