Support Router scopeed RegisterMethod

[wenerme]

Current RegisterMethod will register to global, but some handle do not expected the unknown methods, e.g. a webdav expected PROPFIND, but all other handler are not.

can you explain with an example? I'm having a difficult time understanding what is the issue

[wenerme]

now

chi.RegisterMethod("SEARCH")
r := chi.NewRouter()
r.HandleFunc("/api/v1", func(writer http.ResponseWriter, request *http.Request) {
	// don't expect SEARCH here
	// request.Method
})
r.HandleFunc("/api/v1/webdav", func(writer http.ResponseWriter, request *http.Request) {
	// expect SEARCH here
})

propose

webdav:=r.With()
// RegisterMethod only affect this route
webdav.RegisterMethod("SEARCH")
webdav.HandleFunc("/api/v1/webdav", func(writer http.ResponseWriter, request *http.Request) {
	// expect SEARCH here
})

webdav support alot methods

ACL, CANCELUPLOAD, CHECKIN, CHECKOUT, COPY, DELETE, GET, HEAD, LOCK, MKCALENDAR, MKCOL, MOVE, OPTIONS, POST, PROPFIND, PROPPATCH, PUT, REPORT, SEARCH, UNCHECKOUT, UNLOCK, UPDATE, VERSION-CONTROL

register to global will affect other handler's.
