Adding database authentication via existingSecret #201
Description
Hello,
The current helm chart enforces a mongodb.password field. Where this field is not filled in you will get an error like such:
- Error: INSTALLATION FAILED: execution error at (rocketchat/templates/secret.yaml:25:16): passwords array must have at least one entry
The issue with this is that this chart does not correctly inherit the settings or enable the existingSecrets functionality that the original mongodb bitnami chart does, because it will result in a panic if the password field is missing.
