cluster failover support for c++ and node applications

[nareshv]

Is there any documentation for the cluster level failover for the c++, node.js applications similar to java in https://pulsar.apache.org/docs/3.3.x/client-libraries-cluster-level-failover/ ?

I have come across apache/pulsar-client-cpp#170 discussion, which is closed. It mentions about interface discrepancy in java implementation https://lists.apache.org/thread/cojz6qxpc7v0j8vy0w476ttt0f89zr3z which does not need similar implementation in c++

There is a mention of the pseudo-code in apache/pulsar-client-cpp#170 . But, i don't see any references to updateServiceUrl in the c++ client.

We would need this feature for both c++/node.js based libraries. Any pointers ?
