一共创建了3个 Cluster name，想删除 cluster list， 应该怎么操作。

| Name | Configuration Path | Status (Cached) |

| lo | /root/.obd/cluster/lo | configured |
| test | /root/.obd/cluster/test | deployed |

尝试了使用tenant drop test后，还是存在 CLUster list
[root@z-test-4 cluster]# obd cluster tenant drop test
Deploy “test” is deployed
