Description of problem:
While modifying the already provided permission to client in export block ,refresh config fails with gdeploy

Version-Release number of selected component (if applicable):
gdeploy-2.0.1-5.el7rhgs.noarch
glusterfs-3.8.4-5.el7rhgs.x86_64

How reproducible:
Consistently

Steps to Reproduce:
1.Create 4 node ganesha setup using gdeploy
2.Create a volume with nfs enable on that client
3.Mount the volume to client
4.With gdeploy give permissions to that particular client (say for example provide RO permission to that client).Run refresh-config
5.Modify the RO permission to RW permission (for the same client) using gdeploy refresh config

Actual results:
Refresh Config fails as instead of modifying the same block in export file,it is appending the permission after the block

EXPORT{
      Export_Id= 5 ;
      Path = "/ganeshaval";
      FSAL {
           name = GLUSTER;
           hostname="localhost";
          volume="ganeshaval";
           }
      Access_type = RW;
      Disable_ACL = true;
      Squash="No_root_squash";
      Pseudo="/ganeshaval";
      Protocols = "3", "4" ;
      Transports = "UDP","TCP";
      SecType = "sys";
client {
clients = 10.70.46.30;
allow_root_access = true;
access_type = "RW";
Protocols = "3";
anonymous_uid = 1440;
anonymous_gid = 72;
}

access_type = "RO";
}

     }


Expected results:
Modifying the permission for that particular client should work with gdeploy.It should modify the same export block instead of appending other.
