  system_cfg not read on Oracle datasource

Bug description:
  [ Impact ]

  Prefer system_cfg for network configuration on Oracle above the
  dataousrce config to allow images to dictate network overrides in
  /etc/cloud/cloud.cfg.d when necessary. Without this configuration,
  certain image launches on Orale will not be able to receive correct
  network at VM launch time resulting in inaccessible VMs via SSH.

  [ Test Plan ]

  Procedure for validation (will be scripted as best we can)

  1. Launch Oracle vm for focal, jammy, kinetic and lunar
  2. Confirm presence of /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg 
  3. Upgrade cloud-init to -proposed
  4. confirm absence of /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg
  5. Reboot this VM to test default launch without 99-disable-network-config succeds on fresh launches
  6. sudo cloud-init clean --logs; sudo shutdown -h now
  6. Export VM to Oracle Object Storage
  7. Launch from exported object storage image to trigger reading network config from IMDS instead of ISCSI
  8. Assert ssh to instance works and no Tracebacks in /var/log/cloud-init.log

  [ Where problems could occur ]
  If this patch is unsuccessful, default new instance launches on Oracle or launches from Object storage would timeout and disallow SSH because cloud-init didn't set up network appropriately.

  [ Other Info ]

  [Original description]

  In https://github.com/canonical/cloud-
  init/commit/2c52e6e88b19f5db8d55eb7280ee27703e05d75f , the order of
  reading network config was changed for Oracle due to initramfs needing
  to take lower precedence than the datasource. However, this also
  bumped system_cfg to a lower precedence than ds, which means that any
  network configuration specified in /etc/cloud will not be applied.

  system_cfg should instead be moved above ds so network configuration
  in /etc/cloud takes precedence.
