> Add NFS Gateway support for reading and writing to encryption zones

> Currently, reading and writing within encryption zones does not work through 
> the NFS gateway.
> For example, we have an encryption zone {{/enc}}. Here's the difference of 
> reading the file from hadoop fs and the NFS gateway:
> {code}
> [hdfs@schu-enc2 ~]$ hadoop fs -cat /enc/hi
> hi
> [hdfs@schu-enc2 ~]$ cat /hdfs_nfs/enc/hi
> ??
> {code}
> If we write a file using the NFS gateway, we'll see behavior like this:
> {code}
> [hdfs@schu-enc2 ~]$ echo "hello" > /hdfs_nfs/enc/hello
> [hdfs@schu-enc2 ~]$ cat /hdfs_nfs/enc/hello
> hello
> [hdfs@schu-enc2 ~]$ hdfs dfs -cat /enc/hello
> ???tp[hdfs@schu-enc2 ~]$ 
> {code}
