run_demo (and presumably just_do_it) should not continue when there is a configuration error
I just did a run with run_dumo.sh in which the following error was reported:
Error / ArtException
21-Jul-2018 16:34:23 CDT
UDPMessage 2 / PID 12449
art / Early / JobSetup
cet::exception caught in art
---- Configuration BEGIN
The following were encountered while processing the module configurations:
ERROR: Configuration of module with label randomDelay encountered the following error:
---- Can't find key BEGIN
---- Can't find key END
---- Configuration END
Despite this error, the scripts continued to the running state.
When there is a configuration error, the system should stop at that point and alert the user.
