The create-nodes script currently receives a total # of VMs to create and creates them all, generating their names on the fly. This moves that name generation to lib/ironic and makes the script create only single VMs as directed. This centralizes the naming of things to lib/ironic and will make it easier to reference these things elsewhere. Change-Id: I98e61f7188e027e690303e32aff7cd2347f6d2c2
