Creating the cluster

This time we'll create more services than before so we'll need a bit bigger cluster. It's not that the services will be very demanding but that our VMs have only one CPU and 1GB memory each. Such machines are not something to brag about. This time, we'll create a cluster that consists of five machines. Apart from increasing the capacity of the cluster, everything else will be the same as before, so there's no good reason to go through the process again. We'll simply execute scripts/dm-swarm-5.sh (https://github.com/vfarcic/cloud-provisioning/blob/master/scripts/dm-swarm-5.sh):
