[lunar.lab] Prepare to Deploy TKG Management Clusters to vSphere

• Created a base image template that matches the management cluster’s Kubernetes version.
• Official documentation: https://docs.vmware.com/en/VMware-Tanzu-Kubernetes-Grid/1.5/vmware-tanzu-kubernetes-grid-15/GUID-mgmt-clusters-vsphere.html#import-a-base-image-template-into-vsphere-4
• Import latest available version and -1 to test version upgrade
• In my case for TKGm 1.5.1, I import version Kubernetes v1.21.8 and v1.22.5
• I found out that Ubuntu template is not recognized when trying to deploy workload cluster from TMC, so I also import Photon image.

• Created resource pool and folder for management cluster and each workload cluster. Example:
• tkgmgmt-prod: resource pool and folder to deploy tkg management cluster
• tkc01-dev: resource pool and folder to deploy tkg workload cluster
• tkc02-dev ...
• tkg-template: folder for tkg image template

• Obtain vSphere Certificate Thumbprints
• Official documentation: https://docs.vmware.com/en/VMware-Tanzu-Kubernetes-Grid/1.5/vmware-tanzu-kubernetes-grid-15/GUID-mgmt-clusters-vsphere.html#obtain-vsphere-certificate-thumbprints-8

PS. Please ignore all VMs within resource pool and folder in the screenshot above. I took this screenshot after management cluster and one workload cluster deployed. :D
