This implements a mechanism for post-installation "notifications" via a
POST request [0] when using the auto-installer.
It's implemented as a separate, small utility to facilitate separation
of concerns and make the information gathering easier by having it
isolated in one place.
Patches #1 through #3 are simply clean-ups, refactors, etc. that were
done along the way and can be applied independently.
Most interesting here will be patch #16, which adds the actual
implementation of the post-hook. (Bind-)mounting the installed host
system is done using the existing `proxmox-chroot` utility, and the HTTP
POST functionality can fortunately be re-used 1:1 from
`proxmox-fetch-answer`.
I've also included an example of how the JSON body (pretty-printed and
reduced some things for readability) of such a post-installation request
would look like below, for reference.
Where applicable (and sensible), I have tried to align the format as
much as possible with 1) the format as used in the `fetch-answer` POST
request and 2) PVE's /nodes/<host>/status API endpoint.
Feedback on the post-hook information schema is of course also very much
appreciated!
It should be noted that some information like DMI is generally very
depended on the motherboard/firmware, on what information is actually
available and filled-in. So the contents are expected to vary wildly
between machines and may also be empty, as in the example below from a
VM.
Tested this with both PVE and PBS ISOs, PMG did not (yet) have a
release with an auto-installation capable ISO. The only really
product-specific code is the version detection in `proxmox-post-hook`,
which already handles all three products.

v1: https://lists.proxmox.com/pipermail/pve-devel/2024-July/064580.html
Notable changes v1 -> v2:
* dropped already applied patches & rebased on master
* new fields; now includes ISO version, SecureBoot state, CPU and DMI
info
* product information was split into separate fields & expanded
* boot mode information was split into separate fields
* product version is now retrieved from the package using dpkg-query
directly
* kernel version was split into separate fields
* all disks and NICs are now included, a field indicates whether they
are boot disk or management interface, respectively
* some new cleanup/refactoring patches as noted on v1
(thanks Stefan for the in-depth review!)
