• fixed: Correctly handle GET, HEAD, and OPTIONS requests in ContentLengthLimit.
  Request with these methods are now accepted if they do not have a Content-Length header, and
  the request body will not be checked. If they do have a Content-Length header they'll be
  rejected. This allows ContentLengthLimit to be used as middleware around several routes,
  including GET routes (#989)
• added: Add MethodRouter::{into_make_service, into_make_service_with_connect_info} (#1010)
