title: Neo4j log level in embedded mode
body: <p>In general, i have two questions:</p>
  
  <ol>
  <li><p>Is there a way to disable logging in embedded mode? (I have a db with many deletes/writes and the log gets huge after a while)</p></li>
  <li><p>Can i delete the log files without damaging the "main" database? 
  (nioneo_logical.log.v26, etc... and the lucene logs lucene.log.v13, etc...)</p></li>
  </ol>
  
  <p>Thanks a lot!</p>
