[Request] Add a feature-gate to limit CloneSet pod name length within 63 chars or less.

[veophi]

What would you like to be added:

Align the pod name limitation of CloneSet with Deployment if enable the feature-gate.

Why is this needed:

Pod name may be used as some label value that is limited within 63 chars or less..

@veophi There is a similar issue #1627.

Do you think that if CloneSet supports the use of generateName to randomly generate names by api-server when the length exceeds a certain threshold, it would meet your requirements?

[furykerry]

can the pod name be saved in annotation value instead of label value?
