[HDFS-2615] Parameter dfs.namenode.rpc-address does not get used when determining RPC address of NameNode

Description

When the NameNode is started it listens on two addresses. One defined by "dfs.namenode.servicerpc-address" and the other is derived from fs.defaultFS. It seems like it should check to see if "dfs.namenode.rpc-address" is set to match how getServiceRpcServerAddress.
I have written a patch which updates getRpcServerAddress to achieve this. This means you can set fs.defaultFS to hdfs://hostname/ then set dfs.namenode.rpc-address to 0.0.0.0:8020 and the NameNode will listen on all IP addresses on that machine.
