patch

On Debian systems, when using ifupdown for network configuration with allow-hotplug interfaces (which the installer uses by default) and both slurmd and slurmctld are installed, they fail to start. This happens because allow-hotplug do not guarantee that getaddrinfo succeed after network-online.target is complete [2].
The patch attached retry getaddrinfo five times before giving up and exiting SLURM deamons.
