  [ David Krauser ]
  * buildd: produce kernel and initrd as separate artifacts LP: #1910557

Bug description:
  [Impact]

   * use non --removable uefi installation for cloud-images

   * Currently cloud-images use --removable grub installation, which
  makes the disk images look at lot more like our installer .isos, than
  installed systems.

     This causes many issues:

   * ubuntu efiboot entry is not created by the fallback manager from shim
   * one cannot reorder ubuntu boot entry, and/or boot and apply fwupdate updates (if possible)
   * measurements are unstable, and change if one call grub-install and or upgrades things
   * often grub & shim upgrades are not applied at all as \EFI\ubuntu does not exist on the ESP

   * We should switch to only shipping shim/fallback/mm in \ESP\Boot and
  ship \ESP\ubuntu on the cloud-image ESPs such that we regain stable
  measurements; ubuntu boot entry; and upgrades of grub and shim.

  [Test Case]

   * After UEFI firstboot $ efibootmgr --verbose => should contain
  `ubuntu` entry pointing at ESP\ubuntu\shim*.efi binary, which should
  be added to the bootorder

  [Where problems could occur]

   * Existing systems which were booted from previous style images, will
  not upgrade shim|grub on the ESP, and must call `grub-install` or
  `grub-multi-install` to correct that.
