Error initializing MongoDB (failed to add role clusterMonitor to user)

Hi,

I experience some issues deploying the helm chart v6.4.4 in a test environment. The user_set_role_clusterMonitor.sh generated in mongodb-init-configmap.yaml appears to cause some issues.

Log from the pod:

mongodb 18:55:30.71 INFO  ==> Stopping MongoDB...

This is the relevant configuration from my values.yaml:

mongodb:
  enabled: true
  auth:
    rootPassword: rocketchatroot
    usernames:
      - rocketchat
    passwords:
      - rocketchat
    databases:
      - rocketchat

  architecture: standalone

  persistence:
    enabled: true
    accessMode: ReadWriteOnce
    size: 8Gi

  volumePermissions: { enabled: true }

The issue appears to be in the parsing of the stdout output of mongodb_execute_print_output - unfortunately both my awk- and MongoDB-knowledge isn't too great, otherwise I would have prepared a PR instead of this issue. Is there no better way to detect success?
