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.
