Notes:
* This datasource does not support OCI Classic. OCI Classic provides an EC2
lookalike metadata service.
* The UUID provided in DMI data is not the same as the meta-data provided
instance-id, but has an equivalent lifespan.
* We do need to support upgrade from an instance that cloud-init
identified as OpenStack.
* Bare metal instances use iSCSI root, virtual machine instances do not.
* Both bare metal and virtual machine instances provide a chassis-asset-tag of
OracleCloud.com.

Search network config physical interfaces to see if any of them are
a netfailover master. If found, we prevent matching by MAC as the other
failover devices have the same MAC but need to be ignored.
Note: we rely on cloudinit.net changes which prevent netfailover devices
from being present in the provided network config. For more details about
netfailover devices, refer to cloudinit.net module.
:param network_config
A v1 or v2 network config dict with the primary NIC, and possibly
secondary nic configured. This dict will be mutated.
