Goal: 
To enable the scripts to have granular log levels and specify how much content they want to output, we need to enable this via the rhc-worker-script configuration to let the scripts have their own log level defined.

Acceptance Criteria:

• Introduce a new option to the configuration file that will set the log level to the script
• If no log level is set in the configuration file, use the default one for YGG_LOG_LEVEL that is set by RHCD
• Update rpm packaging file to include the new log level option with a default of `INFO` enabled.
