Add support for storage.redirect.disable=true

[FredNass]

Hello,

Thank you for providing this Helm Chart to the community. We'd like to see support for storage.redirect.disable=true as it would help in situations where S3 storage is not directly accessible to clients. Sorry for not providing the PR as it's a little beyond my skills.

Workaround

In your local config:

docker-registry:
  configData:
    storage:
      redirect:
        disable: true

Yes we found out and it works as expected. Thing is it involves a post-install manual configuration when it could we be managed during the Helm installation. Not a big issue on our side since we made a new Helm Chart (depending on twuni's) and use these settings in its values.yaml but what if not...
