Guidance from Amazon is that if IMDSv2 had disabled token requests
by returning a 403, or cloud-init malformed requests resulting in
other 40X errors, we want the datasource detection to fail quickly
without retries as those symptoms will likely not be resolved by
retries.
Exceptions such as requests.ConnectionError due to IMDS being
temporarily unroutable or unavailable will still retry due to the

asset_tag: 'dmidecode -s chassis-asset-tag'

On Ec2 instances experimentation is that product_serial is upper case,
and product_uuid is lower case. This returns lower case values for both.

@param: network_md: 'network' portion of EC2 metadata.
generally formed as {"interfaces": {"macs": {}} where
'macs' is a dictionary with mac address as key and contents like:
{"device-number": "0", "interface-id": "...", "local-ipv4s": ...}
@param: distro: instance of Distro.
@param: macs_to_nics: Optional dict of mac addresses and nic names. If
not provided, get_interfaces_by_mac is called to get it from the OS.
@param: fallback_nic: Optionally provide the primary nic interface name.
This nic will be guaranteed to minimally have a dhcp4 configuration.
@param: full_network_config: Boolean set True to configure all networking
presented by IMDS. This includes rendering secondary IPv4 and IPv6
addresses on all NICs and rendering network config on secondary NICs.
If False, only the primary nic will be configured and only with dhcp
(IPv4/IPv6).
@return A dict of network config version 2 based on the metadata and macs.
