When running 'kafka-connect create' from cron, we are getting failures

[sasa-tomic]

The command line we are using is

kafka-connect create -c connect-config connect-name

and that works when running outside of a cron job.
But when running inside of a cron job, we're getting the following error:

kafka-connect: error: --from-file and --config cannot be used with input from stdin

Just figured out (after looking at the source code) that the following works:

cat connector-config | kafka-connect create connector-name

Looks like there is a bug in the code which determines whether configuration is provided on the command line. If there's no TTY (and there isn't one in scripted executions such as cron jobs), then kafka-connect doesn't check the --config <connect-config> argument.
