The values.yaml file enables local auth by default and creates a default user.

Describe the bug

The values.yaml file enables local auth by default and creates a default user.:

• https://github.com/concourse/concourse-chart/blob/master/values.yaml#L1093
• https://github.com/concourse/concourse-chart/blob/master/values.yaml#L2855
• https://github.com/concourse/concourse-chart/blob/master/values.yaml#L276

This seems dangerous as a default value. It would be better to include these defaults in the comments and disable local auth by default.

Reproduction steps

1. 2. 3. ...

Expected behavior

No default.

Additional context

No default.
