> The Scala Shell startup script starts a {{FlinkMiniCluster}} by default if invoked with
no arguments.
> We should add a {{--help}} or {{-h}} option to make it easier for people to find out
how to configure remote execution. Alternatively, we could print a notice on the local startup
explaining how to start the shell in remote mode.
