Add support for untagged enums in CRDs #1028

Merged

Motivation

We want to use untagged enums in our CRDs. This allows us to better validate the users input, without the user realizing that under the hood enums are used.

Solution

Extending the Visitor for StructuralSchemaRewriter to rewrite anyOf clauses so that they are accepted by the k8s api-server.

This seems to work fine in my testing. My one concern is that this is basically the same logic as the existing one_of flattening (and seems to be ~93% copy/pasted). Could we factor it out to a separate function that we reuse?

After that I'd be happy to merge.

I think we can get rid of allow_if_equal now and just assume that across the board?

That changes the current implementation for oneOf but sounds reasonable. Adopted!
