Jing Zhao updated HDFS-4947:
----------------------------

    Description: 
This jira adds NFS server export table (hostname or IP range) to control 
export. Specifically, it

1. adds two new classes AccessPrivilege and ClientHostsMatcher for loading and 
checking the mapping between client hosts and their access privileges. These 
two classes are directly copied from Brock Noland's NFS4 implementation.
2. adds the access check (based on the export) to NFS3 procedures.
