The gofumports does everything that gofumpt does with the addition of
formatting imports. This change proposes the use of the `-local` flag so
that we can have imports separated in the following order:
- standard library
- third party
- Talos specific

The gofumpt linter is a stricter drop-in replacement for gofmt. The
rules are ones that I strongly agree with and I think it would be better
if we added this linter instead of nit picking every PR.

This moves to using BLKPG ioctl instead of BLKRRPART. BLKRRPART is older
and more sensitive to EBUSY errors. BLKPG has the potential to minimize
the changes of encountering an EBUSY error when manipulating partition
tables.
In looking at a comparison between BLKPG and BLKRRPART, it seems that
both have their pros and cons. Eventually a combination of the two may
serve us better, but for now I think BLKPG will get us further.

chose ephemeral to make it very clear that the disk should not be used
for application data.

introduces the concept of a mountpoint manager that is capable of
mounting, unmounting, and moving a set of mountpoints in the correct
order.

This uses the correct mount flag for read-only.
We mistakenly had the flag for opening a file as read-only.
