// CenterConfig is configuration for config center
//
// ConfigCenter also introduced concepts of namespace and group to better manage Key-Value pairs by group,
// those configs are already built-in in many professional third-party configuration centers.
// In most cases, namespace is used to isolate different tenants, while group is used to divide the key set from one tenant into groups.
//
// CenterConfig has currently supported Zookeeper, Nacos, Etcd, Consul, Apollo
