> When a descriptor is deployed with discovery configuration, the cluster configuration monitor will begin monitoring the referenced cluster. If that descriptor is subsequently undeployed, and there are no remaining descriptors referencing that same cluster, then the monitor should stop monitoring that cluster configuration.
> Currently, it will continue monitoring such clusters for config changes, and only stop monitoring a cluster if a config change is noticed, at which time it realizes there are no relevant descriptors.
