Bug 1284085

Description of problem:
When running the installer wizard, the host configuration section is confusing as it does not explain what kind of input is expected. There are seemingly unconnected paragraphs of text about what Masters and Nodes do. It is not described however what kind of hostname/IP is expected as input: master, node, or both, or something else.

Version-Release number of selected component (if applicable):
3.1.0

How reproducible:
always

Steps to Reproduce:
1. atomic-openshift-installer install
2. press Y
3. press Enter


Actual results:
following text is displayed:

***Host Configuration***

The OpenShift Master serves the API and web console.  It also coordinates the
jobs that have to run across the environment.  It can even run the datastore.
For wizard based installations the database will be embedded.  It's possible to
change this later using etcd from Red Hat Enterprise Linux 7.

Any Masters configured as part of this installation process will also be
configured as Nodes.  This is so that the Master will be able to proxy to Pods
from the API.  By default this Node will be unscheduleable but this can be changed
after installation with 'oadm manage-node'.

The OpenShift Node provides the runtime environments for containers.  It will
host the required services to be managed by the Master.

Enter hostname or IP address: []: 

Expected results:

Instead of unconnected paragraphs of text - show a description of what this step is actually about: user needs to provide hostnames of all masters/nodes that will take part in the environment that is going to be installed.
