Bug: Failed to run postgres docker container if it is stopped condition during ./setup.sh run

PR Fixes:

• 1 Problem statement: If the shell script found any container of the same name cms-db it uses the same container. This works fine if the container is in running condition. But if the container is stopped then also it tries to use the stopped container and failed to do any postgres related action. The same is shown in the problem video here.
• Problem video:

• 2 Fix: A conditional check is used before starting the postgres container, if the container of name cms-db is running it will stop and remove the container and start it fresh. The same is shown in the solution video here.
