Hi community:
After configuring the geo-replication on Pulsar clusters, the `clusters
list` API will return multiple clusters, including the local Pulsar cluster
and remote clusters like
```
bin/pulsar-admin clusters list
us-west
us-east
us-cent
```
But in this return, you can't distinguish the local and the remote cluster.
When you need to remove the geo-replication configuration, it will be hard
to decide which cluster should be removed on replicated tenants and
namespaces unless you record the cluster information.
### Modification
Add `local` flag to distinguish clusters
```
bin/pulsar-admin clusters list
us-west(local)
us-east
us-cent
```
