logback_default.md

Add default logback.xml

If no logback.xml by user is provided a default logback.xml is loaded. Otherwise use custom logback.xml:

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false" scan="false">

  <logger name="io.micronaut.logging.PropertiesLoggingLevelsConfigurer" levels="WARN" />

  <root level="INFO">
    <autoAppender />
  </root>

</configuration>
