golang ParseURLResponse function does not handle URLs correctly

[burgerdev]

The function ParseURLResponse does not accept URLs, only paths. Providing a URL as input does not fail, but produces unexpected results.

• The function is used correctly in server.go, but the naming and documentation is misleading.
• The HandshakeInfo seems to be computed correctly.
• The Message is wrong.

Example code with output:

package main

import (
	"fmt"
	"log"

	"github.com/google/glome/go/glome"
	"github.com/google/glome/go/login"
)

func main() {
	srv := login.Server{KeyFetcher: func(_ uint8) (*glome.PrivateKey, error) {
		var key glome.PrivateKey
		key[5] = 1
		return &key, nil
	}}
	resp, err := srv.ParseURLResponse("https://glome.example.com/v1/UYcvQ1u4uJ0OOtYqouURB07hleHDnvaogAFBi-ZW48N2/serial-number:123/reboot/")
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("login.Message%+v\n", resp.Msg)
}

login.Message{HostIDType:https HostID: Action:/glome.example.com/v1/UYcvQ1u4uJ0OOtYqouURB07hleHDnvaogAFBi-ZW48N2/serial-number:123/reboot}

6648ac8 changed the ParseURLResponse implementation. Running the program listed above, results now the correct output:

login.Message{HostIDType:serial-number HostID:123 Action:reboot}

There are still ways to improvement that function but I believe we can do it as a part of #102.
