Can we please move this to a follow-up series? This is harder to follow
in part because test/py/tests/test_ut.py is the only test that calls
fs_helper.setup_image with second_part=True, but then maybe I'm just
missing it, doesn't do anything with it, we just need an empty partition
to exist?

I'd like to take the first part of this series, then convert the
fs_helper.mk_fs using tests. Then convert test_ut.py (which is
open-coded fallocate/mkfs.vfat/etc calls) to the new class. Then
understand what DiskHelper really needs to do. Perhaps include having a
case where multiple (and non-empty secondary) partitions are used. Then
we'll know we have both the right abstraction and that it works. Thanks.
