[mlok-nokia]

Why I did it

redis_chassis process fails to start in the database-chassis on the supervisor card.

How I did it

The redis and redis_chassis processes in supervisor.conf has been modified to start with 'redis' as user. The modification only added redis and redis group for database containers except database-chassis container. This commit adds code to the docker-database-init.sh to add redis and redis group for the database-chassis to address this issue.

How to verify it

Booting the image on Supervisor. And verify the database-chassis container should be in UP state, and the database-chassis.service is in active(running) state

admin@ixre-cpm-chassis15:~$ docker ps -a
