This PR can be split into two parts:
* controllers
* apid binding into COSI world
Controllers
-----------
* `k8s.EndpointController` provides control plane endpoints on worker
nodes (it isn't required for now on control plane nodes)
* `secrets.RootController` now provides OS top-level secrets (CA cert)
and secret configuration
* `secrets.APIController` generates API secrets (certificates) in a bit
different way for workers and control plane nodes: controlplane nodes
generate directly, while workers reach out to `trustd` on control plane
nodes via `k8s.Endpoint` resource
apid Binding
------------
Resource `secrets.API` provides binding to protobuf by converting
itself back and forth to protobuf spec.
apid no longer receives machine configuration, instead it receives
gRPC-backed socket to access Resource API. apid watches `secrets.API`
resource, fetches certs and CA from it and uses that in its TLS
configuration.

This moves endpoint refresh from the context of the service `apid` in
`machined` into `apid` service itself for the workers. `apid` does
initial poll for the endpoints when it boots, but also periodically
polls for new endpoints to make sure it has accurate list of `trustd`
endpoints to talk to, this handles cases when control plane endpoints
change (e.g. rolling replace of control plane nodes with new IPs).

Instead of doing our homegrown "try all the endpoints" method,
use gRPC load-balancing across configured endpoints.
Generalize load-balancer via gRPC resolver we had in Talos API client,
use it in remote certificate generator code. Generalized resolver is
still under `machinery/`, as `pkg/grpc` is not in `machinery/`, and we
can't depend on Talos code from `machinery/`.
Related to: #3068
Full fix for #3068 requires dynamic updates to control plane endpoints
while apid is running, this is coming in the next PR.

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.

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.
There should be no functional changes with this PR.

This makes `pkg/config` directly importable from other projects.

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.

This PR cleans up the formatting for various package imports as they
were causing the linter to throw errors.
