LFX-Mentorship-Fall: StatefulSet support volume claim resize

[tianzichenone]

What would you like to be added:
Auto resize PVC capacity when updating volume claim template in Advanced StatefulSet and CloneSet.

And should consider the following things:

• How to check StorageClass(CSI Driver) support resize capacity of PV?
• How to let users know whether the resize is successful?
• Should we rebuild Pod (and PVC) if the CSI Driver does not support resize PV (especially for CloneSet)?
• Align with the design of upstream: KEP-0661: StatefulSet volume resize kubernetes/enhancements#3412

Why is this needed:
When we want to expand all PVCs of StatefulSet or CloneSet ， we should update PVCs manually.
When we update capacity in volume claim template, the newly created Pods will use updated capacity, but the old Pods not, this confusing the user.

@tianzichenone Thanks. If upstream is working on this kubernetes/enhancements#2842 , we'd better wait for it and then rebase into Kruise, to make sure the behavior is consistent with upstream.
