This re-arranges phases a bit so that shutdown actions are pushed back
to the top-level main.go of machined.
Small rudimentary event.Bus is introduce to facilitate event passing
(shutdown/restart) between various machined components and main.go. This
might be not the best implementation, just something to allow this
message passing without global variables or such.
Machined API was refactored to run as goroutine service.
ACPI & signal handlers re-built as phase tasks, and activated for
non-container, container modes respectively.
As part of the fix, now `docker stop` triggers correct shutdown of Talos
(not a big deal, but good for testing).

It is now possible to `start`/`stop`/`restart` any service via `osctl`
commands.
There are some changes in `ServiceRunner` to support re-use (re-entering
running state). `Services` singleton now tracks service running state to
avoid calling `Start()` on already running `ServiceRunner` instance.
Method `Start()` was renamed to `LoadAndStart()` to break up service
loading (adding to the list of service) and actual service start.
