Keys with dots/periods and slashes

[adrmaas]

I'm trying to assess config-lint for use in testing of helm charts and I'm not sure how to handle a common key formatting style without success. A common strategy for many applications is make annotations or labels that come in a format that includes dots and slashes. For example this snippet from the kali helm chart:
https://github.com/narenarjun/go-grpc-k8s-serverless/blob/c6184aae7945abbc519299d7ac5bf1032569bf3b/kubernetes/setup/istio/add-ons/kiali-install.yaml#L448-L462

I've been unable to find a way to escape forward slashes (/) or dots (.) in keys that are found in labels and annotations like:

  labels:
    app.kubernetes.io/name: kiali

Perhaps I've missed it in the documentation but I can't find any reference to an escape character either in the GitHub repository or the documentation site.

This has the effect of making it impossible to test many critical labels and annotations that operators or ingress routers depend on for the successful running of an application/service.

Any information regarding escaping characters in keys would be greatly appreciated!
