Validate CRDs created by `mirrord operator setup`

[t4lz]

We could run https://github.com/openshift/crd-schema-checker on CI.

The SQS CRDs generate "NoMaps" errors because I didn't know it was bad practice, I think we should not change old CRDs now but we can use it to have better standards for new CRDs and new changes.
