Deployed Server - get-occ-config.sh need ordered host list

Browse Source 
Make note in documentation that it is critical to list hosts
according to node %index% number when using get-occ-config.sh
to distribute Heat agent config for pre-deployed servers.

If the nodes are not listed in the correct order the Heat
config added will/can be for a different node.

@ -606,10 +606,35 @@ environment variable, and corresponding ``$<role-name>_hosts`` variables.
Overcloud deployment. These role names correspond to the name of the roles from
the roles data file used during the deployment.
Each ``$<role-name>_hosts`` variable is a space separated list of IP addresses
that are the IP addresses of the deployed servers for the roles. For example,
in the above command, 192.168.25.1 is the IP of Controller 0, 192.168.25.2 is
the IP of Controller 1, etc.
Each ``$<role-name>_hosts`` variable is a space separated **ordered** list of
IP addresses that are the IP addresses of the deployed servers for the roles.
For example, in the above command, 192.168.25.1 is the IP of Controller 0,
192.168.25.2 is the IP of Controller 1, etc.
.. Note:: The IP addresses for the hosts in the ``$<role-name>_hosts`` variable
must be **ordered** to avoid Heat agent configuration mismatch.
Start with the address for the node with the lowest node-index and
count from there. For example, when deployed server IP addresses are:
* overcloud-controller-0: 192.168.25.10
* overcloud-controller-1: 192.168.25.11
* overcloud-controller-2: 192.168.25.12
* overcloud-compute-0: 192.168.25.20
* overcloud-compute-1: 192.168.25.21
The variables must be set as follows.
(**The order of entries is critical!**)
For Controllers::
# controller-0 controller-1 controller-2
ControllerDeployedServer_hosts="192.168.25.10 192.168.25.11 192.168.25.12"
For Computes::
# compute-0 compute-1
ComputeDeployedServer_hosts="192.168.25.20 192.168.25.21"
The script will take care of querying Heat for each request metadata url,
configure the url in the agent configuration file on each deployed server, and
