While the QEMU QAPI schema describes 'lun' as a number, the code dealing with JSON strings does not strictly adhere to this schema and thus formats the number back as a string. Use the new helper to retrieve both possibilities. Note that the formatting code is okay and qemu will accept it as an int. Tweak also one of the test stringst to verify that both formats work with libvirt.
