get_pod_name was observed to return a list of all
pods satisfying the query without consideration of
the state of the pod. In one observed scenario the name of
a runing pod and an terminating pod were returned.
All subsequent commands used the podname with out checking
for multiple entries. They clearly expect only a single
name, not multiple.
Modify get_pod_name to only return a single rinning pod name.
