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="true" scan="false">

 <include resource="io/kokuwa/logback/base.xml" />

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

 <root level="INFO">
  <appender-ref ref="${LOGBACK_APPENDER:-CONSOLE}" />
 </root>

</configuration>
