zhiyong.dai 26a74d4596 Add choices for option '--policy'
When creating server group, the '--policy' option is required, but
valid choice is 'affinity' or 'anti-affinity', adding multiple
policies will produce an error. This patch add choices and default
value for option '--policy', and remove the former help message.
