@xulinfei1996 Please add some use cases, why should they be limited to a list of namespaces?

Please add some use cases, why should they be limited to a list of namespaces

@hormes Koordinator ElasticQuota can support all namspaces by default. On this basis, a namespace list is added to limit, which can be compatible with internal scenarios, such as ACK ElasticQuotaTree.
