Description

The octl iaas A describe B commands used a single output option (--output yaml,single) to output only the first entry returned by the Read api call.

octl iaas A describe B -o json would drop the single output option, and return a list, not an object.

This PR replaces the output option with a new --single flag, allowing octl iaas A describe B and octl iaas A describe B -o json to both return an object.
