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.

Fixes were applied automatically.
Import ordering might be questionable, but it's strict:
* stdlib
* other packages
* same package imports

This moves `pkg/config`, `pkg/client` and `pkg/constants`
under `pkg/machinery` umbrella.
And `pkg/machinery` is published as Go module inside Talos repository.

Package `pkg/crypto` was extracted as `github.com/talos-systems/crypto`
repository and Go module.

This make the config provider a pure interface definition by removing
all concrete internal types, and making them an interface.

This makes `pkg/config` directly importable from other projects.
There should be no functional changes.

Fixes#2272
`gofumpt` is now included into `golangci-lint`, but not the
`gofumports`, so we keep it using it as separate binary, but we keep
versions in sync with `golangci-lint`.
This contains fixes from:
* `gofumpt` (automated, mostly around octal constants)
* `exhaustive` in `switch` statements
* `noctx` (adding context with default timeout to http requests)

This is a rewrite of machined. It addresses some of the limitations and
complexity in the implementation. This introduces the idea of a
controller. A controller is responsible for managing the runtime, the
sequencer, and a new state type introduced in this PR.
A few highlights are:
- no more event bus
- functional approach to tasks (no more types defined for each task)
- the task function definition now offers a lot more context, like
access to raw API requests, the current sequence, a logger, the new
state interface, and the runtime interface.
- no more panics to handle reboots
- additional initialize and reboot sequences
- graceful gRPC server shutdown on critical errors
- config is now stored at install time to avoid having to download it at
install time and at boot time
- upgrades now use the local config instead of downloading it
- the upgrade API's preserve option takes precedence over the config's
install force option
Additionally, this pulls various packes in under machined to make the
code easier to navigate.

When images are pulled by Talos or via CRI plugin, configuration
for each registry is applied. Mirrors allow to redirect pull request to
either local registry or cached registry. Auth & TLS enable
authentication and TLS authentication for non-public registries.
