Description of problem:
Currently gdeploy works for adding permissions to 1 client only.
Fails to add permissions to more than 1 client.

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:


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 2 or more clients.Run refresh-config

[hosts]
dhcp46-241.lab.eng.blr.redhat.com
dhcp46-219.lab.eng.blr.redhat.com
dhcp47-159.lab.eng.blr.redhat.com
dhcp47-3.lab.eng.blr.redhat.com


[nfs-ganesha]
action=refresh-config
config-block=clients = 10.70.46.60;|allow_root_access = false;|access_type = "RW";|Protocols = "3";|anonymous_uid = 1440;|anonymous_gid = 72;
config-block=clients = 10.70.46.44;|allow_root_access = true;|access_type = "RO";|Protocols = "4";|anonymous_uid = 1440;|anonymous_gid = 72;
volname=ganeshaval


Actual results:
Refresh config fails to provide permissions to more than 1 client

Expected results:
gdeploy should provide permissions to any no. of client and refresh config should work with it.
