Warnings in logs for Ubuntu minimal images

[catmsred]

Bug report

On Azure integrations tests with a minimal Ubuntu image, verify_clean_log failed due to partitioning errors. The problem seems to be that sgdisk is not installed by default and is not an explicit dependency of cloud-init.

Steps to reproduce the problem

Create an Azure minimal image with cloud-init using the cc_disk_setup config Search logs for errors

Environment details

• Cloud-init version: 99.daily-202402231934-89ebcc39~ubuntu23.10.1,
• Operating System Distribution: Ubuntu
• Cloud provider, platform or installer type: Azure minimal image,
