log explosion on failure

Key: CHUKWA-416
URL: https://issues.apache.org/jira/browse/CHUKWA-416
Project: Hadoop Chukwa
Issue Type: Bug
Components: build and test code
Reporter: Ari Rabkin
When the filesystem dies, collectors should exit in an orderly way. Instead, we
get an explosion of log messages, since the daemonwatcher tries to deregister a
shutdown hook during shutdown, triggering exceptions.
