Description of problem:

Adding a node to an rhsc cluster through the rest api does not create iptable rules on the node. 

Version-Release number of selected component (if applicable):
rhsc-cb10

How reproducible:
100%

Steps to Reproduce:
1. create a fresh gluster node
2. in rhsc create a cluster
3. via rest api add a node to the cluster

4. ssh into the node and run `service iptables status`

Actual results:

Table: filter
Chain INPUT (policy ACCEPT)
num  target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
num  target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
num  target     prot opt source               destination
