Description
The NameNode has duplicate SSL listener code - the new code in HttpServer from HADOOP-8581 and the original Hsftp code in NameNodeHttpServer. Let's remove the SSL code from NameNodeHttpServer and make any modifications to Hsftp to work with the SSL implementation from HADOOP-8581. This may be tricky if we want to ensure the 2.x Hsftp client works with 1.x servers.
