This patch adds the ability to specify a cleaning and provisioning
network for Ironic. If none are specified then Ironic continues to
function as it does now.
Ironic role will calculate the UUID of the neutron network assuming a
network name is provided.
Additionally, this is added to testing by configuring a network to add
with the network-name.
