Provide method to determine if a deprecated key was set in the config file
--------------------------------------------------------------------------

                 Key: HADOOP-6252
                 URL: https://issues.apache.org/jira/browse/HADOOP-6252
             Project: Hadoop Common
          Issue Type: Improvement
          Components: conf
    Affects Versions: 0.21.0
            Reporter: Jakob Homan
            Assignee: Jakob Homan


HADOOP-6105 provided a method to deprecate config keys and transparently refer to the new
key. However, it didn't provide a method to see if the deprecated key had been used in the
config file.  This is useful when, if the deprecated key had been used, its value needs to
be converted before use, for instance when we changed the umask format.  A method like "boolean
wasDeprecatedKeySet()" would be great.  Patch shortly.
