Options allow for changes in commands behavior. This commit introduces the QCO_NO_SUCCESS_RESP option, which causes a command to not emit a success response. This is needed by commands such as qemu-ga's guest-shutdown, which may not be able to complete before the VM vanishes. In this case, it's useful and simpler not to bother sending a success response.
