> Allow viewing Cassandra related system properties.
> Viewing yaml config settings, as implemented by {{SettingsTable}} in
> CASSANDRA-14573, is not enough for certain third-party tool use-cases. There
> are a number of system properties that can be define that also contribute to
> the configuration set that Cassandra runs on.
> An example of such a use-case is described in CASSANDRA-15339. JMX ports need
> to be discovered, especially in 4.0 where multiple nodes can run on one
> ipaddress. Unlike the native port that is through gossip discoverable, the
> jmx port is not. The jmx port is also not available via the SettingsTable.
> With this patch and {{SystemPropertiesTable}} it becomes possible to first
> discover all the native ports in the cluster and against each then discover
> each node's jmx port.
