Bug Description

Related to this bug: https://bugs.launchpad.net/ubuntu-image/+bug/1630709

We currently do new='{}M:+{}K'.format(part.offset // MiB(1), ceil(part.size / 1024)) when doing a call to sgdisk. We also do some assumptions that offsets are 1MiB min earlier in the code.

Realistically speaking we need to switch to 1KiB being the min (not feasible to have more precision as sgdisk accepts 1K as the smallest, or sector numbers).

I think we should dupe this bug to LP: #1630709 and handle both cases in the same branch. See my other comments to that bug.
