helm:bugfix - handle kubernetes ingress api depreciation (#545)

The extensions/v1beta1 and networking.k8s.io/v1beta1 API versions
of Ingress are no longer supported in v1.22. Platform helm files were no
able to handle with this changes. This pull request adds a validation
to check the cluster version and use a correct ingress api version.
