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.

The primary NIC configuration should not be modified based on the IMDS
values, as it should continue to be configured for DHCP. As such, this
uses the instance's network config dict which is expected to have the
primary NIC configuration already present.
It will mutate the network config to include the secondary VNICs.
:raises:
Exceptions are not handled within this function. Likely
exceptions are KeyError/IndexError
(if the IMDS returns valid JSON with unexpected contents).
