Changing host/port on an existing client for reconnection

A feature request: give the ability to update the connection settings of an existing client in place, so that it can reconnect to a different host if necessary after creation. For connections that stay open a long time, sometimes the remote Redis host gets redeployed on a new server, and it would be nice to be able to use a shared client and update it.

e.g.

const client = redis.createClient({ host: "1.2.3.4"  });
client.on("reconnecting", function() {
  // oops, the host has moved since a week ago
  client.setOptions({ host: "5.6.7.8" });
});

I'd imagine that calling .setOptions() on a connected client would also force a disconnect/reconnect.

Does this make sense? Is there a workaround to do this already that I'm missing?

Review the client creation, connection-options, and reconnecting entry points illustrated by createClient, setOptions, and the reconnecting event. Determine the intended behavior for changing host or port on a connected client, including whether it forces reconnection; the issue names no files or tests, so add coverage for the agreed behavior.
