title: Dropwizard default logback pattern
body: <p>Does anyone knows the default format pattern for Dropwizard 0.7.1 logging, if no logFormat is configured?</p>
  
  <p>I need sth like:</p>
  
  <pre><code>%d{HH:mm:ss.SSS} %-5level [%X{id}] [%X{format}] [%thread]: %class{0}::%method:%line - %msg%n
  </code></pre>
