Implement SELinux labeling support in EtcFileController, label both squashfs and runtime-created files in /etc and /system/etc.
Add corresponding test cases.

- replace `interface{}` with `any` using `gofmt -r 'interface{} -> any -w'`
- replace `a = []T{}` with `var a []T` where possible.
- replace `a = []T{}` with `a = make([]T, 0, len(b))` where possible.

This PR adds a new controller - `DNSServerController` that starts tcp and udp dns servers locally. Just like `EtcFileController` it monitors `ResolverStatusType` and updates the list of destinations from there.
Most of the caching logic is in our "lobotomized" "`CoreDNS` fork. We need this fork because default `CoreDNS` carries
full Caddy server and various other modules that we don't need in Talos. On our side we implement
random selection of the actual dns and request forwarding.
Closes#7693

As the controller reconciles every /etc file present, it might be called
multiple times for the same file, even if the actual contents haven't
changed.
Rewriting the file might lead to some concurrent process seeing
incomplete file contents more often than needed.

There's a cyclic dependency on siderolink library which imports talos
machinery back. We will fix that after we get talos pushed under a new
name.

Containerd doesn't support merging plugin configuration from multiple
sources, and Talos has several pieces which configure CRI plugin:
(see https://github.com/containerd/containerd/issues/5837)
* base config
* registry mirror config
* system extensions
* ...
So we implement our own simple way of merging config parts (by simply
concatenating text files) to build a final `cri.toml`.
At the same time containerd migrated to a new format to specify registry
mirror configuration, while old way (via CRI config) is going to be
removed in 1.7.0. New way also allows to apply most of registry
configuration (except for auth) on the fly.
Also, containerd was updated to 1.6.0-rc.0 and runc to 1.1.0.

This implements two controllers: one which generates templates for
`/etc/hosts` and `/etc/resolv.config`, and another generic controller
which renders files to `/etc` via shadow bind mounts.
