Subject: [PATCH] Flush confirmation messages

Confirmation messages for cluster, profile, policy, receiver and node
deletions are printed using sys.stdout.write.  However sys.stdout.write
output is line-buffered [1].  Since the confirmation message does not
contain a newline, the message may not appear in the user's terminal.
