        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
        callsite wait_for_url.

    @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
