Catch exception thrown by zmq when it recieves a signal and make HiPeRTA quit when this happends. Note: if we need a more complex behaviour such as sleep/reloadConfig/restart we will need :
- to separate zmq from signal (which is apparently not supposed to be possible because zmq seems to use signals for some functionnalities)
- or we will have to use a dedicated zmq socket with dedicated port and host for that
