Distributor will silently fail to start if it can't find a config file

[timpokorny]

Summary

If you start the distributor without a config file it will silently fail. You can generate this one of two ways. Either cd into the bin directory and run ./distributor.sh (which will look by default for etc/distributor.config and not find it), or from the directory above, run bin/distributor.sh --config-file nope.

In either case, the application will just fail to start. Tested on Linux but suspect this will affect the same across platforms.

Reproduction Steps

• cd into $DISCO_HOME/bin and run ./distributor.sh OR
• cd into $DISCO_HOME and run bin/distributor.sh --config-file no-such-file
