[litmus] mongodb rootPassword is converted to an integer

[wrdls]

The default rootPassword gets automatically converted to an int by YAML parser libraries.

This makes the env of the post-upgrade-hook Job look like this:

          env:
            - name: DB_PASSWORD
              value: 1234
            - name: DB_USER
              value: root

Which is not a valid Job because env values need to be strings.

Change the default to something that will always be a string (e.g. abc123) or make sure to apply proper quoting with the | quote function.

Haven't checked the whole chart but it's at least an issue here: https://github.com/litmuschaos/litmus-helm/blob/master/charts/litmus/templates/post-upgrade-hook.yaml#L43

The upgrade job has been removed in 3.x for now. So this issue shouldn't be happening. Closing this issue, feel free to open if the issue still persists. Thanks!
