Add ability to stream Hadoop metrics through syslog appender 
-------------------------------------------------------------

                 Key: CHUKWA-545
                 URL: https://issues.apache.org/jira/browse/CHUKWA-545
             Project: Chukwa
          Issue Type: New Feature
          Components: data collection
            Reporter: Eric Yang
            Assignee: Eric Yang
             Fix For: 0.5.0


Hadoop metrics is currently streaming through Chukwa's customized log4j appender to delegate
the registration of metrics file with Chukwa agent.  Both Chukwa agent and chukwa hadoop client
keeps track of list of registered adaptors.  It is error prone to have adaptor list tracked
in two different places.  In addition, the management of metrics files is also a problem.
 Hence, I propose to remove both limitation by using syslog appeender to send hadoop metrics
to Chukwa.  This approach eliminates the adaptor and file management problems.
