Debugging / Logging

Feign is used as the underlying REST library. Sometimes it is useful to see the low level JSON and responses. It is possible to setup debug without directed to stdout or to a log file. This is simplified by set the environment variable DEBUG_JSON_OUTPUT to either a file name debug.log or to System.out.
