ciao-controller: All running instances status should be 'active'
ciao-controller: All running instances status should be 'active'

When asking for a specific instance details or a list of instances
details, the status string for a running instance should be
consistent.
Then, for OpenStack compatibility sake, we want this string to
be 'active' and not 'running'.

Fixes #323
