    Shouldn't this be `./flink [--configDir <configDir>] <ACTION> 
[ACTION-OPTIONS] [ARGUMENTS]`?

> At the moment there is no other way than the environment variable 
> FLINK_CONF_DIR to specify the configuration directory for the CliFrontend if 
> it is started via the flink shell script. In order to improve the user 
> exprience, I would propose to introduce a {{--configDir}} parameter which the 
> user can use to specify a configuration directory more easily.
