contrail-docker - contrail-analytics - contrail-ansible: redis configuration not consistent in multi-interface setup

after deploying contrail networking 4.1.0 for Ubuntu 16.04 Ocata with contrail-charms in a multi-interface setup, it can be seen that the redis configuration for contrail-analytics is not functional in all cases.

/etc/contrailctl/analytuics.conf has the following addresses configured:

[GLOBAL]
controller_nodes = 172.30.14.2,172.30.14.3,172.30.14.4
analyticsdb_nodes = 172.30.14.2,172.30.14.3,172.30.14.4
analytics_nodes = 172.30.14.2,172.30.14.3,172.30.14.4

The interfaces on the server/docker container are as follows (as seen from ansible):
root@cldsv00003(analytics):/# cat << 'EOF' > ansible-test.yaml
> - hosts: all
> gather_facts: yes
> tasks:
> - debug: var=ansible_all_ipv4_addresses
> EOF
root@cldsv00003(analytics):/# ansible-playbook -i contrail-ansible-internal/playbooks/inventory/all-in-one ansible-test.yaml

        "172.17.0.1"
    ]
}

From the redis configuratino it can be seen that only the first interface is chosen which is actually a different interface as configured in the contrail configuration.

Solution would be to either:
- configure localhost for redis for all services using redis on the analytics container OR
- make sure the configured address space is used for the redis bind configuration
