Parser cache is configured by default, causing warning when it's missing
The parser cache is enabled by default in Kafo::Configuration::DEFAULT with it set to ./config/parser_cache.json.
This causes a warning to be logged unnecessarily when it hasn't been generated, since the scenario/app config is merged with the defaults. It should be an optional feature.
