Review Comment:
   The command now changes its return value from the raw Java/protobuf label 
list to an Array of Ruby Strings (label_string). There are existing cluster 
tests for other visibility label shell commands, but none currently cover 
list_labels; adding a test would protect this return-type/contents change 
(e.g., create a label, wait until available, then assert command(:list_labels, 
'TEST_.*') includes the label and that returned elements are String).
