The only remaining part is filtering out SideroLink addresses when Talos
looks for a node address.
See also https://github.com/talos-systems/siderolink/pull/2
The way to test it out:
```
$ talosctl cluster create ... --extra-boot-kernel-args
siderolink.api=172.20.0.1:4000
```
(where 172.20.0.1 is the bridge IP)
Run `siderolink-agent` (test implementation):
```
$ sudo _out/siderolink-agent-linux-amd64
```
Now on the host, there should be a `siderolink` Wireguard userspace
tunnel:
```
$ sudo wg
interface: siderolink
public key: 2aq/V91QyrHAoH24RK0bldukgo2rWk+wqE5Eg6TArCM=
private key: (hidden)
listening port: 51821
peer: Tyr6C/F3FFLWtnzqq7Dsm54B40bOPq6++PTiD/zqn2Y=
endpoint: 172.20.0.1:47857
allowed ips: fdae:41e4:649b:9303:b6db:d99c:215e:dfc4/128
latest handshake: 2 minutes, 2 seconds ago
transfer: 3.62 KiB received, 1012 B sent
...
```
Each Talos node will be registered as a peer, tunnel is established.
You can now ping Talos nodes from the host over the tunnel:
```
$ ping fdae:41e4:649b:9303:b6db:d99c:215e:dfc4
PING fdae:41e4:649b:9303:b6db:d99c:215e:dfc4(fdae:41e4:649b:9303:b6db:d99c:215e:dfc4) 56 data bytes
64 bytes from fdae:41e4:649b:9303:b6db:d99c:215e:dfc4: icmp_seq=1 ttl=64 time=0.352 ms
64 bytes from fdae:41e4:649b:9303:b6db:d99c:215e:dfc4: icmp_seq=2 ttl=64 time=0.437 ms

Fixes#4407fixes#4489
This PR started by enabling simple restart of the `kubelet` service via
services API, but it turned out there's a problem:
When kubelet restarts, CNI is already up, so there's an interface on the
host with CNI node IP, the code which picks kubelet node IP finds it and
tries to add it to the list of kubelet node IPs which completely breaks
kubelet.
Solution was easy: allow node IPs to be filtered out - e.g. we never
want kubelet node IP to be from the pod CIDR.
But this filtering feature is also useful in other cases, so I added
that as well.

Fixes#4279
These APIs were deprecated in 0.13, now it's time to drop them for 0.14.
They were not used anywhere in Talos, so no changes on Talos side.

This updages CoreDNS from 1.8.4 which includes many fixes from upstream.
Also this seems to fix timeouts introduced in the change which added
`rewrite stop type AAAA A` rule to the `Corefile`.

Brings udev rules as first class citizens in the machine config
Allows for customizing how udev devices are presented in the system. My case in particular, I need to change the group and permissions for the Intel QuickSync renderer device to enable non-root containers to make use of the hardware transcoding capabilities of the Intel GPU.

This enables cluster discovery by default for Talos 0.14. KubeSpan is
