Zookeeper ports collide when during ensemble-add.

Issue

• When a second set of fabric is created in the same servers, the zookeeper ports will collide when ensemble-add resets the zookeeper ports to 2181,2812,2183 etc.
• The fabric is created using min-port and max-port to avoid the collision. But it does not help.

fabric:create --new-user admin --new-user-password admin --new-user-role admin --zookeeper-password admin --zookeeper-server-port 3181 --min-port 3000 --max-port 3999 --wait-for-provisioning
fabric:join --zookeeper-password admin --min-port 3000 --max-port 3999 HKLPATRCW01:3181
