Bug description:
  Following on from previous similar package update requests @ LP:
  #2073164, LP: #2066314, LP: #2033061 and LP: #2020770 this bug is a
  request to update gce-compute-image-packages to the upstream version
  `20241010.00` @ https://github.com/GoogleCloudPlatform/guest-
  configs/releases/tag/20241010.00

  This package has an SRU exception @
  https://wiki.ubuntu.com/StableReleaseUpdates#gce-compute-image-
  packages including an ageing exception detailed @
  https://wiki.ubuntu.com/gce-compute-image-packages-Updates

  [Impact]

  This package is provided by Google for installation within guests that
  run on Google Compute Engine. It is part of a collection of tools and
  daemons, that ensure that the Ubuntu images published to GCE run
  properly on their platform.

  Cloud platforms evolve at a rate that can't be handled in six-month
  increments, and they will often develop features that they would like
  to be available to customers who don't want to upgrade from earlier
  Ubuntu releases. As such, updating this package to more recent
  upstream releases is required within all Ubuntu releases, so they
  continue to function properly in their environment.

  [Test Case]

  When a new version of this package is uploaded to -proposed, the
  following will happen:

   * an image based on -proposed will be built for GCE and published to the ubuntu-os-cloud-devel project
   * the GCE team will be asked to validate that the new package addresses the issues it is expected to address, and that the image passes their internal image validation.

  If all the testing indicates that the image containing the new package
  is acceptable, verification will be considered to be done.

  [Vendored Dependencies]

  There were no vendoring changes in these releases (OO/NN/JJ/FF)

  [Where Problems Could Occur]

  There are many upstream changes in `20241010.00-0ubuntu1` vs.
  `20240607.00-0ubuntu1`; however between the guest-test-infra suite [0]
  (which is run for validation by CPC _and_ Google) and CPC's own
  internal test harness (CTF), there is confidence that most if not all
  "edge cases" and/or obvious regressions concerns can be dismissed
  before the new version lands in `-updates`

  That being said, there are changes to the `pre-inst` and edits to how
  the instance hostname is created/validated. There are also significant
  changes to network config management, OSLogin, SSH access and
  networkctl/dhclient in this bug's "sister" at LP: #2084498. We should
  be mindful of all these changes as they could possibly cause instances
  to become inaccessible. To mitigate this there are several CTF suites
  that will trigger an instance reboot (e.g. google_disk_size,
  google_shutdown_script, google_shutdown_script_url, etc.). There is
  also a specific job we have internally that will create an instance
  from a "normal" image, and gradually install each guest-agent package
  from -proposed with reboots in between. Assuming all this works as
  expected we can be assured we've mitigated.

  [Other Information]

  This bug is used for tracking of releasing the new upstream version
  for all supported series, as per the approved policy mentioned in the
  following MRE:

  https://wiki.ubuntu.com/gce-compute-image-packages-Updates

  The updated package is not built for armhf and riscv64 due to upstream
  regressions but the package is not used on those architectures thus
  please release the SRU without the armhf and risc64 binaries.

  The package does not build for powerpc on Xenial, but this is OK since
  it is not used on powerpc either.
