Ubuntu Autoinstall default network identifier
The Ubuntu Autoinstall cloud-init provisioning template relies on a network identifier name for its network setup. Currently, the default name ens160 is used which works only for a specific hardware type. Instead of using a default identifier name, we propose making use of the MAC-matching field.
It allows us to use the MAC (which is known during deployment) instead of the system-generated network identifier (which relies on the compute resource hardware).
