☑️ Prevent deprecated APIs in Kubernetes v1.17

The v1.17 release stopped serving some API versions for different resource types. When a user deploys a resource with a deprecated API version, the Kubernetes engine rejects it.

Kubernetes v1.17 is no longer (officially) supported since 30 January 2021, So if you are still running this version, consider upgrading it as soon as possible.
