Rene Moser 0c1257b0c1 cloudstack: cs_instance: deploy instance in desired state on state=started/stopped
Before this change, an instance must be present for make use of state=stopped/started. Now we are deploying an instance in the desire state if it does not exist.

In this case all args needed to deploy the instance must be passed. However the short form for stopping/starting an _existing_ instance still works as before.
