Make sync/async start/stop request.

Do not try to request start not fully installed computer partition, and wait
until instance setup packing list is stopped, before trying to create hosting
one.

Beside of setting state on Software instance by start/stop requested methods
setup in activities real request. Thanks to this *after* computer partition is
installed (instance setup packing list == stopped) the request becomes
synchronous (...a bit later -- in sense -- just once called).
