Add k8s support feature set and Add platform label for scheduler usage (sonic-net#12997)

Why I did it
We plan to pilot k8s feature, need to fix several bugs including enable telemetry feature and add platform label.

How I did it
Add support feature set, only enable telemetry container upgrade for now
Add platform label for scheduler usage
Remove CNI installation code, it would be auto installed when install kubeadm
How to verify it
After sonic device join k8s cluster, show node labels to check if platform label is visible.
