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

...

Expected behavior

No default.

Additional context

No default.
