In order to perform upgrades the way we would like, it is important that
we avoid any bind mounts into containers. This change ensures that all
system services get their config via stdin.

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

The goal of `pkg/grpc/tls` is to generate `*tls.Config` based on some
input parameters, but it had dependency on `pkg/grpc/gen` for 'remote'
certificate provider (it uses trustd client to sign CSRs).
Package `pkg/client` which is a part of future `machinery/` module
depends on `pkg/grpc/tls` for TLS config generation, so this pulls
`pkg/grpc` into `machinery/`, while it's not really good idea as most of
`pkg/grpc` is about server-side gRPC handling.
So the idea is to move `pkg/grpc/tls` (which has nothing to do with
gRPC), to `github.com/talos-systems/crypto/tls`, so we need to make sure
it has no dependencies on other Talos code.
The idea of this refactoring is to squash local & remote certificate
renewing providers as they had common part extracted, but even after
that almost all the code was identical except for different generators
beind used.

This PR cleans up the formatting for various package imports as they

This PR will allow users to set the `persist: true` value in their
config data to tell talos not to re-pull the config data at each reboot.
The default will still remain as a "pull every time" methodolgy in order
to encourage immutability by default.

In `tls.Config`, there are two hooks for getting certificate for client
and server config. So we need separate configuration methods to
configure them both.
Required in apid to provide refreshing TLS client cert to
grpc.ClientConn.

Logging is pretty simple and bare minimum is being logged. I believe
better logging can be provided for apid when it does fan-out, but that
is beyond the scope for the first PR.
Sample logs:
```
$ osctl-linux-amd64 logs machined-api

This installs default middleware to recover from panics (convert them to
errors) in all the grpc servers by default.
Slight refactoring to allow that as grpc can only accept Unary/Stream
interceptors only once.

This moves from translating a config into an internal config
representation, to using an interface. The idea is that an interface
gives us stronger compile time checks, and will prevent us from having to copy
from on struct to another. As long as a concrete type implements the
Configurator interface, it can be used to provide instructions to Talos.

This detangles the gRPC client code from the userdata code. The
motivation behind this is to make creating clients more simple and not
dependent on our configuration format.

The gofumports does everything that gofumpt does with the addition of
formatting imports. This change proposes the use of the `-local` flag so
that we can have imports separated in the following order:
- standard library
- third party
- Talos specific

The gofumpt linter is a stricter drop-in replacement for gofmt. The
rules are ones that I strongly agree with and I think it would be better
if we added this linter instead of nit picking every PR.

We should still support username and password for backwards compatibility.

This implements insecure over-file-socket gRPC API for init with two
first simplest APIs: reboot and shutdown (poweroff).
File socket is mounted only to `osd` service, so it is the only service
which can access init API. Osd forwards reboot/shutdown already
implemented APIs to init which actually executes these.
This enables graceful shutdown/reboot with service shutdown, sync, etc.
