Use UUID for topic consumer instance
Modified the code so that if the consumer group is defined, but the consumer instance is not, then policy-endpoints will generate a UUID for the consumer instance. Made the logic a little more straight-forward in response to a review comment. Issue-ID: POLICY-3405 Change-Id: If74440bdb01525bc463a28e5b8a9a2eca89a855a Signed-off-by: Jim Hahn <jrh3@att.com>
