Log flush should complete upon broker shutdown
----------------------------------------------
Key: KAFKA-126
URL: https://issues.apache.org/jira/browse/KAFKA-126
Project: Kafka
Issue Type: Bug
Reporter: Joel Koshy
Broker shutdown currently forces the flush scheduler to shutdown(Now). This
leads to an unclean shutdown. cleanupLogs may be affected by a similar scenario.

A possible fix this would be to use shutdown() instead of shutdownNow() in the
scheduler.
