Update git submodules
* Update docs/submodules/fuel from branch 'master'
- Merge "ci/deploy.sh: maas: cleanup_uefi on env erase"
- ci/deploy.sh: maas: cleanup_uefi on env erase
Running `ci/deploy.sh -EE` should also perform an UEFI boot option
cleanup, otherwise we risk booting the previously installed OS.
While at it, reduce delay between nodes removal and fix a rare failure
for `-EE` when no nodes are defined in MaaS.
