feat(init): implement graceful shutdown of 'init' (#562)
Most crucial changes in `init/main.go`: on shutdown now Talos tries
to stop gracefully all the services. All the shutdown paths are unified,
including poweroff, reboot and panic handling on startup.

While I was at it, I also fixed bug with containers failing to start
when old snapshot is still around.

Service lifecycle is wrapped with `ServiceRunner` object now which
handles state transitions and captures events related to state changes.
Every change goes to the log as well.

There's no way to capture service state yet, but that is planned to be
implemented as RPC API for `init` which is exposed via `osd` to `osctl`.

Future steps:

1. Implement service dependencies for correct startup order and
shutdown order.

2. Implement service health, so that we can say "start trustd when
containerd is up and healthy".

3. Implement gRPC API for init, expose via osd (service status, restart,
poweroff, ...)

4. Impement 'String()' for conditions, so that we can see what service
is waiting on right now.
