Move Delegation token into Common so that we can use it for MapReduce also
--------------------------------------------------------------------------

                 Key: HDFS-949
                 URL: https://issues.apache.org/jira/browse/HDFS-949
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley


We need to support a MapReduce job that launches another MapReduce job inside its Mapper.
Since the task doesn't have any Kerberos tickets, we need a delegation token. Moving the HDFS
Delegation token to Common will allow both projects to use it.
