python/machine: Add debug logging to key state changes

When key decisions are made about the lifetime of the VM process being
managed, there's no log entry. Juxtaposed with the very verbose runstate
change logging of the QMP module, machine seems a bit too introverted
now.

Season the machine.py module with logging statements to taste to help
make a tastier soup.
