Retire TKC object in case of version mismatch between the TKC and cluster object.

Products

• Tanzu Kubernetes Runtime

Issue/Introduction

• There is a version mismatch between the TKC object and Cluster object.
• While attempting to update the TKC object to the desired version, following error is seen:
  error: tanzukubernetesclusters.run.tanzu.vmware.com "<tkc-name>" could not be patched: admission webhook "default.validating.tanzukubernetescluster.run.tanzu.vmware.com" denied the request

Environment

vSphere Kubernetes Service

Cause

• The TKC object and cluster object need to be on the same version in order to retire the TKC object from the environment. 
• This version mismatch is usually seen if Cluster version is updated on a TKC Cluster, which is not recommended. (Recommendation is to update TKC, not the Cluster object)
