Log:
Fix https://issues.apache.org/bugzilla/show_bug.cgi?id=52184

- * <ul>
- * <li>NOTHING: Log nothing.</li>
- * <li>DEBUG_ALL: Log all problems at DEBUG log level.</li>
- * <li>INFO_THEN_DEBUG: Log first problem at INFO log level and any further
- * issues in the following TBD (configurable) seconds at DEBUG level</li>
- * <li>INFO_ALL: Log all problems at INFO log level.</li>
- * </ul>
- * By default, INFO_THEN_DEBUG is used with a suppression time of 24 hours.
