   This command is to delete a cluster's metadata. As you can see, the `/admin/clusters` node may contain two nodes:
   
   ```bash
   $ ls /admin/clusters 
   [global, my-cluster]
   ```
   
   Here `my-cluster` is the `clusterName` defined in `conf/broker.conf`. When we have multiple clusters that share the same configuration store, if we deleted the whole `/admin` node, other clusters would be affected.
   
   The same goes for `/ledgers` node when multiple clusters share the same bookie cluster.
   
   As for the other nodes under `/ledgers` and `/admin`, it should be deleted by the related admin operations. For example, when you delete a topic, the broker will delete all associated ledgers, which contains the nodes in ZK (`/ledgers/00/0000/L<ledger-id>`). We should not delete these nodes manually.
