Public bug reported:
[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.
