Andrew Rynhard 49307d554d refactor: improve machined
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.
