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 keeps backwards compatibility with `osctl` CLI binary with the
exception of `osctl config generate` which was renamed to `osctl
gen config` to avoid confusion with other `osctl config`
commands which operate on client config, not Talos server config.
Command implementation and helpers were split into subpackages for
cleaner code and more visible boundaries. The resulting binary still
combines commands from both sections into a single binary.

I added tests for all the commands which work reliably in container mode.
Some tests are naive, some are more sophisticated. While going
through the tests, I think I found a small bug in `osctl gen keypair`.
When we get reliable KVM tests, I can revisit and add missing
tests for time, reboot, shutdown and friends.
