Provide methods for obtaining delegation token from Namenode for hftp and other
uses

Key: HDFS-994
URL: https://issues.apache.org/jira/browse/HDFS-994
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Jakob Homan
Assignee: Jakob Homan
In hftp, destination clusters will require an RPC-version-agnostic means of
obtaining delegation tokens from the source cluster. The easiest method is
provide a webservice to retrieve a token over http. This can be encrypted via
SSL (backed by Kerberos, done in another JIRA), providing security for
cross-cluster hftp operations.
