@qiujian16 do we have any docs to describe the clusterclaim

[qiujian16]

the design doc is here https://github.com/open-cluster-management-io/enhancements/tree/main/enhancements/sig-architecture/4-cluster-claims. But it will be good if we also have doc here to briefly describe it.

FYI @elgnay
