--dualTLS Initialize both TLS and non-TLS ports for all shards.
The non-TLS ports will be the TLS ports + 1500.
Only effective when TLS is active (see `useTLS`).

--tlsCluster Enable TLS for cluster communication. Only effective
when TLS is active (see `useTLS`) and when running
in cluster mode. (default: True)
