More specifically, pick up `/etc/resolv.conf` contents by default when

Dynamically map Kubernetes and Talos API ports to an available port on
the host, so every cluster gets its own unique set of parts.
As part of the changes, refactor the provision library and interfaces,
dropping old weird interfaces replacing with (hopefully) much more
descriprive names.

This PR ensures that we can test our siderolink communication using embedded siderolink-agent.
If `--with-siderolink` provided during `talos cluster create` talosctl will embed proper kernel string and setup `siderolink-agent` as a separate process. It should be used with combination of `--skip-injecting-config` and `--with-apply-config` (the latter will use newly generated IPv6 siderolink addresses which talosctl passes to the agent as a "pre-bind").

`talosctl cluster show` currently reports '-' in the CPU and RAM
columns because these informations are not available directly from the
container list API call.
For consistency with `talosctl cluster create`, this commit fetches the
missing information through an inspect call for each node so that these
information are available from a `Reflect` initialization.

When provisioning VMs, each launch process sets up CNI network, and from
time to time CNI setup fails with something like:
```
error provisioning CNI network: plugin type="firewall" failed (add): running [/sbin/iptables -t filter -N CNI-ADMIN --wait]: exit status 4: iptables v1.8.10 (nf_tables)
```
This a race condition in the CNI plugins, and it looks like there is no
fix for it (see e.g. https://github.com/hashicorp/nomad/issues/8838).
As a workaround, take a mutex around CNI operation to serialize them.
CNI setup happens in different processes, so use a file-based mutex.

The core blockdevice library already supported resolving symlinks, we
just need to get the raw block device name from it, and use it
afterwards.
In QEMU provisioner, leave the first (system) disk as virtio (for
performance), and mount user disks as 'ata', which allows `udevd` to
pick up the disk IDs (not available for `virtio`), and use the symlink
path in the tests.

The static paths for the OVMF firmware are limited, and won't match, for
example, any of the files installed by `edk2-ovmf` on a Fedora 38 system. This
change separates the search paths and filenames, making sure all combinations
are covered when looking for a suitable firmware. Similarly also cleans up the
OVMF vars lookup.

Add flags for configuring the qemu bridge interface with chaos options:
- network-chaos-enabled
- network-jitter
- network-latency
- network-packet-loss
- network-packet-reorder
- network-packet-corrupt
- network-bandwidth
These flags are used in /pkg/provision/providers/vm/network.go at the end of the CreateNetwork function to first see if the network-chaos-enabled flag is set, and then check if bandwidth is set. This will allow developers to simulate clusters having a degraded WAN connection in the development environment and testing pipelines.
If bandwidth is not set, it will then enable the other options.
- Note that if bandwidth is set, the other options such as jitter, latency, packet loss, reordering and corruption will not be used. This is for two reasons:
- Restriction the bandwidth can often intoduce many of the other issues being set by the other options.
- Setting the bandwidth uses a separate queuing discipline (Token Bucket Filter) from the other options (Network Emulator) and requires a much more complex configuration using a Heirarchial Token Bucket Filter which cannot be configured at a granular enough level using the vishvananda/netlink library.
Adding both queuing disciplines to the same interface may be an option to look into in the future, but would take more extensive testing and control over many more variables which I believe is out of the scope of this PR. It is also possible to add custom profiles, but will also take more research to develop common scenarios which combine different options in a realistic manner.

This adds support for automatically registering node hostnames in DNS by
sending the current hostname to DHCP via option 12. If the current hostname is
updated, issue a new DISCOVER to propagate the update to DHCP (updating the
hostname on lease renewals is not universally supported by DHCP servers). This
addition maintains the previous functionality where the node can also request
its hostname from the DHCP server. The received hostname will be processed and
prioritized as usual by the `network.HostnameSpecController`.
This change set also contains fixes to make DHCP renewals compliant with RFC
2131, specifically avoiding sending the server identifier and requested IP
address when issuing renewals using a previous offer. This also uncovered
issues and missing features in the upstream `insomniacslk/dhcp` library, the
fixes and improvements for which are now finally merged.
Sending hostname updates have been tested against `dnsmasq` and the built-in
DHCP + DNS services in Windows Server. Hostname retrieval from DHCP and edge
cases with overridden hostnames from different configuration layers have been
extensively tested against `dnsmasq`.
