Configuration file discovery
Some configuration file formats (JSON, YAML) require additional runtime
dependencies. If a such dependency is missing, configuration file location
will stop and not try other configuration files with lower priority.
E.g. if I have both log4j2.json and log4j2.xml in classpath, but not
Jackson (required for JSON config), then no configuration file will be
loaded and I get this error:
ERROR StatusLogger No log4j2 configuration file found. Using default
configuration: logging only errors to the console. Set system property
'org.apache.logging.log4j.simplelog.StatusLogger.level' to TRACE to show
Log4j2 internal initialization logging.
When enabling status logging TRACE, I get a lot of logging (see below) and
it's not so easy to figure out what went wrong.
Would it make sense to emit a more explicit error message on WARN level
when this occurs?

Perfect!
This is the kind of thing I had in mind with the "ergonomics" epic. Relatively minor tweaks that can make troubleshooting a lot easier for users.
