Aren't we switching v1alpha4 to v1beta2?

@gab-satchi
I feel really bad about this because I opened the issue behind this PR, but now that I see that removing v1beta1 is impacting v1alpha3 I don't think we can move on with this change, otherwise we can't ensure a clean v1alpha3 --> v1alpha4 upgrade.
This change has to wait for v1alpha3 being removed before 😞
Sorry again for not having considered this when opening the issue

[vincepri]

We should probably mostly drop support / deprecate in this release, rather than removing the APIs altogether. In the next release, we should be able to proceed with the complete removal, alongside the v1alpha3 API types.

No worries @fabriziopandini. let me know if it makes more sense to close and re-open when the time is right
