[DNS] Support binding to sub-interfaces
---------------------------------------

                 Key: HADOOP-7806
                 URL: https://issues.apache.org/jira/browse/HADOOP-7806
             Project: Hadoop Common
          Issue Type: New Feature
          Components: util
    Affects Versions: 0.24.0
            Reporter: Harsh J
            Assignee: Harsh J


Right now, with the {{DNS}} class, we can look up IPs of provided interface names ({{eth0}},
{{vm1}}, etc.). However, it would be useful if the I/F -> IP lookup also took a look at
subinterfaces ({{eth0:1}}, etc.) and allowed binding to only a specified subinterface / virtual
interface.

This should be fairly easy to add, by matching against all available interfaces' subinterfaces
via Java.
