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.

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

Status big `STA_UNSYNC` should be cleared otherwise kernel assumes that
time is not sync. `STA_PLL` is set to notify kernel that we apply offset
adjustments periodically.

Talos depends on accurate time for many actions, so many services depend
on timed successful health check. If timed fails to do initial sync, it
enters pretty long wait loop for the next attempt which might not come
in time for the boot timeout. Instead, fail timed service on initial
sync and rely on service restart for another attempt.

This linter makes sure tests are excercising only public package API.
I fixed all the tests which touch only public API of the packages. For
other test packages I added proper `//nolint` directive.

This should be proper way to adjust time incrementally without causing
jumps one in +/- direction. Time-sensitive services might be confused by
huge jumps.
This also implements timed healh check based on first successful time
sync.
Fixed some random health check related issues in other services.

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.
