refactor: change pointer to struct

[suzuki-shunsuke]

BREAKING CHNAGE: change the signature of structs

• Ensure the transport isn't changed

Migration

• Route.Matcher: *Matcher -> Matcher
• Route.Tester: *Tester -> Tester
• Route.Response: *Response -> Response
• Tester.Test: func(*testing.T, *http.Request, *Service, *Route) -> func(*testing.T, *http.Request, Service, Route)
• &Transport -> Transport
