[crd-gen] Possibility to add extra information to fields

[andreaTP]

Is your enhancement related to a problem? Please describe

The most self-explanatory example is the type format hint allowed in the CRD such as:

weight:
  description: weight associated with matching
    the corresponding podAffinityTerm, in the
    range 1-100.
  format: int32
  type: integer

Currently the generator emits only the type information and we don't have, at best of my knowledge, any way to express a specific format.

I'm opening this ticket more widely in the hope that we can agree on a solution that will cover additional use-cases:

• x-kubernetes-list-type
• pattern
• format
• default
• nullable
• ...

but I'm open to evaluate specific solutions (e.g. one per missing property).

Describe the solution you'd like

A possible solution, again, is a new custom annotation, even if some of those fields might be extracted more automagically by the generator (e.g. nullable and default).

Describe alternatives you've considered

Is this still applicable? Is there still interest on this?

I think it's still compelling, but let see ...
