Talos always supported that, but CRI config lacked support for it.
Now with recent containerd the new `_default` host is used as a
fallback, so this re-enables the support and updates the docs.

There was inconsistency in the way `/v2` was appended to registry
endpoint path between containerd (CRI) and Talos:
* Talos only appended `/v2` to empty paths
* containerd appended `/v2` if it's not the suffix already
Fix Talos to act same as containerd, and introduce a setting
`overridePath` which stops both Talos and `containerd` from appending
`/v2` (should be required with e.g. Harbor registry mirror).

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.

We should preserve the order of keys in generated `hosts.toml`, but
go-toml library has no real way to do that on marshaling, so fix the
previous workaround, as it was generating invalid TOML.

There should be no functional change with this PR.
The primary driver is supporting strategic merge configuration patches.
For such type of patches machine config should be loaded from incomplete
fragments, so it becomes critically important to distinguish between a
field having zero value vs. field being set in YAML.
E.g. with following struct:
```go
struct { AEnabled *bool `yaml:"a"` }
```
It's possible to distinguish between:
```yaml
a: false
```
and no metion of `a` in YAML.
Merging process trewats zero values as "not set" (skips them when
merging), so it's important to allow overriding value to explicit
`false`.

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.
