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.

Fixes#1906
This provides lifetime as duration relative to kubeconfig generation
time (the moment `osctl kubeconfig` was called).

This extracts admin kubeconfig generation out of bootkube, now based on
Talos x509 library. On each API request for `kubeconfig`, config is
generated on the fly and sent back on the wire.
This fixes two issues:
* any master node can now generate `kubeconfig` (worker nodes can do
that too, but that should probably change in the future)
* after upgrade-and-wipe the disk scenario, `osctl kubeconfig` still
works
