Net::IP accepts a myriad of different IP objects from ranges to
prefixes to singular IPs. We check if the object consists only of a
singular IP and normalize the IP if it has size 1 (since then it
could still be a /32 prefix or a range consisting of one IP).
Otherwise we would theoretically accept any valid Net::IP object here.

This simplifies the comparison of IPs by using the object-oriented
interface over the procedural one. Also instantiate the ips using the
new method rather than using new, which isn't a keyword in Perl. This
fixes the respective perlcritic warning.

Because of how the Netbox IPAM plugin works (utilizing IP ranges to
represent DHCP ranges), we need a hook in the IPAM plugin that runs on
updates to the subnet because DHCP ranges can be edited. The update
hook in Netbox checks which DHCP ranges got added and which got
deleted and then performs the respective changes in the Netbox IPAM.
This operates under the assumption that DHCP ranges do not overlap
(which is not supported by Netbox anyway).
Only Netbox needs to do work on update, so we can leave this as noop
in phpIPAM and the PVE IPAM, because they have no notion of IP ranges
or similar entities. phpIPAM doesn't support DHCP ranges at all and
PVE IPAM simply uses DHCP ranges as a constraint when allocating an
IP.
I decided on this approach over just creating IP ranges on demand when
assigning IPs, because this keeps Netbox clean and in sync with the
PVE state. It doesn't leave remnants of IP ranges in the Netbox
database, which can lead to errors when trying to create IP ranges
that overlap with IP ranges that already existed in an SDN subnet.
This method tries to check for any possible errors before editing the
entities. There is still a small window where external changes can
occur that lead to errors. We are touching multiple entities here, so
in case of errors users have to fix their Netbox instance manually.

Create a helper method that abstracts the common code used in making
netbox requests. Move all api_request incovations over to using the
helper method. This saves us from writing lots of repeated code.
This also updates the helpers and introduces error checking there.
Helpers didn't catch any errors and the invoking methods didn't as
well. This meant that functions with $noerr set to 1 would still error
out. We now pass $noerr to the helper functions and they behave the
same as the parent methods. This requires some additional checks in
the call sites of the helpers.
Also canonicalize all URLs, since Netbox does that and it saves us a
redirect.

Currently, we do not verify the TLS certificate for API requests
external IPAM and DNS integration. This could allow man-in-the-middle
attacks, albeit most IPAM infrastructure is on controlled and isolated
LANs, so it's not something that should frequently happen; and
technically our IPAM integration is still marked as tech-preview,
which had its reasons.
Enforce verification, and allow users to pass a cert SHA256
fingerprint to ensure a certificates validity if it's not trusted by
the system trust store, as it's, e.g., the case for self-signed certs.
The code was adapted from the one in pve-apiclient, which we cannot
reuse directly as it is only implemented for requests against PVE
nodes, not as a generic HTTP client request helper.
Add the new dependency `libio-socket-ssl-perl` required to get the
verify callback for the TLS certificate used for cert-fingerprint
checking.

The conditional assignment caused falsy values to be converted to
undef when comparing them. This led to the behavior that configuration
values that are interpreted by perl as falsy would get wrongly
compared and always show up as pending changes.
As an example the 'bgp-multipath-as-path-relax' or 'ebgp' keys of the
bgp controller configuration are booleans and get stored as 0 in the
controller configuration when they're turned off. They always showed
up as a pending change, because of the behavior described above.

We opted for a simple copy of the legacy file to the new location,
since any other migration path would be too strenuous. The worst-case
scenario of failures with this approach is losing IPAM / MAC entries
that are created during the update window in the legacy files by nodes
that are not yet updated to the new version. Those can be fixed by a
simple start / stop of the affected VMs, triggering a rewrite of the
IPAM database.

This does not contain data that needs to be protected to avoid
hijacking (external) systems, like our credentials for certain storage
types or encryption keys, so placing it in the strictly root-only
'priv/' folder was always a bit overkill.
Now we want to make the firewall more SDN aware and thus need also to
parse the SDN config there. This means having to also read the IPAM
statefile here, and as of now we would need to move over quite a few
API endpoints to be proxied to the privileged pvedaemon running as
root, as otherwise they would fail to read the full SDN config & state
required.
That is not a big problem, but it's also not really nice, we got the
privilege separation for a reason after all. Thus, move the backing
file for the PVE IPAM plugin state over to the general /etc/pve/sdn
path, where www-data (and thus pveproxy) can read it, but still not
write it. Fallback to the old location for backward compatibility.
This way the file will be automatically written to the new place on
the first change. This is not fool-proof, but there's only so much we
can do here to support a sane upgrade path, so fall back to a base
requirement of all cluster nodes using the same package versions.
FWIW, Stefan Hanreich tested a very similar diff I sent to him
off-list, but it was not close enough to add a T-b now.
