There was a problem hiding this comment.
please comment the history and reason of why we need "fix" template hash. It seems that previously we only has controllerrevisionhash in the pod

Ⅰ. Describe what this PR does
Optimize inplace update and support
pod-template-hashlabel for cloneset.Now there are two hash labels in pods that managed by cloneset:
controller-revision-hashis still the important one that indicates the pod version. It defaults to be"{CLONESET_NAME}-{HASH}", and it will be"{HASH}"if user enabled theCloneSetShortHashfeature-gate.pod-template-hashshould always be the short format"{HASH}". cloneset-controller will not rely on it, but some other controllers, such as kruise-rollout, may use it to be the service selector.
