Fix unknown field problems after change to CRD apiVersion check

[lspecian-olx]

Description

The CRD apiVersion check introduced a validation problem due to changes on the resource type schema

Importance

zookeeper-operator chart can't be installed on EKS versions supporting apiextensions.k8s.io/v1

Location

https://github.com/lspecian-olx/zookeeper-operator/blob/master/charts/zookeeper-operator/templates/zookeeper.pravega.io_zookeeperclusters_crd.yaml#L3

Suggestions for an improvement

The template needs to accommodate both api versions apiextensions.k8s.io/v1 and apiextensions.k8s.io/v1beta1 in order to continue to provide support for eks versions without support for apiextensions.k8s.io/v1
