CRD generation should support validation schema for optional struct

[droot]

Kubebuilder generated validation schema in CRD doesn't support optional struct. It specifies the optional field with type: object that prevents the input manifest for a CR to omit it completely.

One of the ways to represent optional struct in validation schema would be:

"anyOf:
- type: null
- type: object

refer: kubernetes/apiextensions-apiserver#25

Alternatively, you could use oneOf, but it really doesn't make a difference.

This is what // +nullable would be for, but it should be under CT.
