Daemons should be able to log if log4j.properties specifies sufficient logging

ACCUMULO-2334 Remove ACCUMULO_LOG_HOST in favor of pull host and port log-forwarding from zookeeper

I was able to do logging with only log4j.properties. However, that doesn't work anymore. All my daemons have this as the last line of their logs:

2014-02-14 14:23:38,049 INFO org.apache.accumulo.server.Accumulo: Zookeeper connected and initialized, attemping to talk to HDFS
2014-02-14 14:23:38,067 INFO org.apache.accumulo.server.watcher.MonitorLog4jWatcher: Changing monitor log4j address to 10.20.93.170:4560
2014-02-14 14:23:38,067 INFO org.apache.accumulo.server.watcher.MonitorLog4jWatcher: Enabled log-forwarding

Note that I don't use generic_logger.xml, and this wasn't a requirement for 1.4. But now it seems there is no logging if *_logger.xml files are not present (as ACCUMULO-2349 has also reported).
