…rectly after adding xmpp auth knobs

Closes-Bug: #1549663, SMLite - lbass and ceilometer parameters are not updated in the cluster json from testbed.py

testbed.py specify as follows
env.enable_lbaas = True
env.xmpp_auth_enable = True
env.xmpp_dns_auth_enable = True
enable_ceilometer = True

cluster.json specify as follows USE lower case true or false, conf parser at agent/controller is not liking the True/False.
root@a3s14:~# more cluster.json
{
    "cluster": [
        {
            "id": "cluster_auto_652",
            "parameters": {
                "enable_ceilometer": "true",
                "xmpp_auth_enable": "true",
                "xmpp_dns_auth_enable": "true"
            }
        }
    ]
}
