Move the test data into their own files to allow for easier testing and adding data.
Add logging support which will go to the console and to syslog to help troubleshoot issues with this script.
This function says its for assigning the portgroups but its really for creating portgroups which can be used for tagged network traffic.
This helper method will create our management network portgroup for traffic.
Correct how we parse and look for an associated link for a given network.
VMware wants the VMkernel interfaces, which are the logical interfaces, that get the IP address assigned to them to follow the vmkX pattern where X is an integer starting from 0.
The network configuration that this script aims to bring up is the management network so that someone can log into the hypervisor and then finish configuring it. This makes adjustments to how the IP interfaces are assigned to include their MAC address and the MTU for the network to bring up the networks. Updates the configuration of the interfaces to support DHCP as well as static IPv4 addresses.
Once the host is configured for all of our settings to take effect we need to reboot the machine.

When booting these images in an OpenStack environment Neutron and OVN are configured with the MAC addresses that the Neutron port. This means that when we use the IPs associated with these ports for sending and receiving traffic the interface that's used needs to use this MAC address as well. This configures the logical VMkernel interface with the MAC address that comes from the config drive which is coming from Neutron.
Additionally this series adds some extra logging to assist with debugging and troubleshooting. Renamed a few functions for clarity and added a final reboot to ensure that the machine is on the network configs as expected.
