The idrac-bootstrap.yml playbook is intended to bootstrap network configuration
of the iDRACs on a set of Dell servers. By default, iDRACs have a known static
IP address (192.168.0.120) and a set of default credentials configured. Since
all iDRACs have the same default IP address, we need a way to isolate a single
iDRAC while we set its network configuration. We do this using a temporary VLAN
accessible from one of the controllers.
