"konduit serve" CLI: Confusing error when configuration path does not exist

[AlexDBlack]

konduit serve -c does-not-exist.json -id demo_server gives the error below.
What actually happened here was I had a typo in the name of the JSON file. However, rather than "file X does not exist" I got a very confusing error, because the CLI was attempting to interpret the filename as an actual JSON string (because it wasn't a valid path).

Given configuration: 'does-not-exist.json' does not contain a valid JSON/YAML object

Errors while processing as a yaml string:
java.lang.IllegalStateException: Expected JsonNode to be ObjectNode but was TextNode while parsing as a YAML object. This usually indicates that the YAML was not parsed as expected. Could be a bad configuration file path in: does-not-exist.json
