Setup a Neutron network for use Ironic

In the general case, the Neutron network can be a simple flat network. However, in a complex case, this can be whatever you need and want. Ensure you adjust the deployment accordingly. The following is an example:

neutron net-create cleaning-net --shared \
                                --provider:network_type flat \
                                --provider:physical_network ironic-net

neutron subnet-create ironic-net 172.19.0.0/22 --name ironic-subnet
                                               --ip-version=4 \
                                               --allocation-pool start=172.19.1.100,end=172.19.1.200 \
                                               --enable-dhcp \
                                               --dns-nameservers list=true 8.8.4.4 8.8.8.8
