This eliminates one place in which we currently need to mirror changes to the script-land Cluster::Node record. Instead of keeping an exact in-core equivalent, the Supervisor now treats the data structure as opaque, and stores the whole cluster table as a JSON string. We may replace the script-layer Supervisor::ClusterEndpoint in the future, using Cluster::Node directly. But that's a more invasive change that will affect how people invoke Supervisor::create() and similars. Relying on JSON for serialization has the side-effect of removing the Supervisor's earlier quirk of using 0/tcp, not 0/unknown, to indicate unused ports in the Supervisor::ClusterEndpoint record.
