Bug Description

zookeeper in contrail-analyticsdb container runs a separate cluster listening on port 2182 per default (as compared to 2181 on contrail-controller) as per
https://github.com/Juniper/contrail-ansible-internal/blob/54978053db9159b6c7ad49c12c8a713c150e28f2/playbooks/roles/contrail/common/defaults/main.yml#L56

It is expected that analytics services connect to the zookeeper cluster running on analyticsdb. However, analytics services are configured with the same zookeeper list/port as the controller, e.g.:
https://github.com/Juniper/contrail-ansible-internal/blob/5442c0f52101f4a6bb251c079978c03dbe90c796/playbooks/roles/contrail/analytics/tasks/collector.yml#L12

where zk_servers_with_port is defined here derived from zk_server_list: https://github.com/Juniper/contrail-ansible-internal/blob/4d2569e858a9ea08296266f9c7235af975bc49f1/playbooks/roles/contrail/common/vars/main.yml#L11

and zk_server_list is derived from config_server_list: https://github.com/Juniper/contrail-ansible-internal/blob/54978053db9159b6c7ad49c12c8a713c150e28f2/playbooks/roles/contrail/common/defaults/main.yml#L47

Need fix for 4.1.

2 Things:

1. Bug is applicable to 4.1.x only and not 5.x, hence marking 5.x instances as invalid.
2. Bug is for analytics team to look into.

In R5.0 and trunk, analytics services already point to analyticsdb zookeeper instance. Hence no fix is needed.
