OCI provides a OpenStack like metadata service which provides only
'2013-10-17' and 'latest' versions..
Notes:
* This datasource does not support the 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.
* Both bare-metal and vms use iscsi root
* Both bare-metal and vms provide chassis-asset-tag of OracleCloud.com

Fetch data from Oracle's IMDS, generate secondary NIC config, merge it.
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
takes an existing network_config dict which is expected to have the primary
NIC configuration already present. It will mutate the given dict to
include the secondary VNICs.
:param network_config:
A v1 or v2 network config dict with the primary NIC already configured.
This dict will be mutated.
:raises:
Exceptions are not handled within this function. Likely exceptions are
those raised by url_helper.readurl (if communicating with the IMDS
fails), ValueError/JSONDecodeError (if the IMDS returns invalid JSON),
and KeyError/IndexError (if the IMDS returns valid JSON with unexpected
contents).

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.

considered at all if there is is kernel/initramfs provided

overrides datasource provided data and does not consult here.

Each path listed in the index will be represented in the dictionary.
If the path ends in .json, then the content will be decoded and
