Use PAUSED state for domains that are starting up

Browse Source 
When libvirt is starting a domain, it reports the state as SHUTOFF until
it's RUNNING. This is not ideal because domain startup may take a long
time (usually because of some configuration issues, firewalls blocking
access to network disks, etc.) and domain lists provided by libvirt look
awkward. One can see weird shutoff domains with IDs in a list of active
domains or even shutoff transient domains. In any case, it looks more
like a bug in libvirt than a normal state a domain goes through.
