Description
===========
If the same IP is used for any of these options in undercloud.conf:
local_ip undercloud_admin_host undercloud_public_host
It will cause issues with the endpoints and haproxy for services. In this specific case, the zaqar_ws haproxy service was using the same bind and server IP address.
Steps to reproduce
==================
1. Define the same IP address for local_ip and undercloud_public_host as the same address:
local_ip = 192.168.24.2/24
undercloud_public_host = 192.168.24.2
undercloud_admin_host = 192.168.24.3
2. openstack undercloud install
3. Try to deploy the overcloud.
Expected result
===============
Undercloud install should throw an error advising that this can't be done.
Actual result
=============
Traceback:
clean_up DeployOvercloud: Handshake status 502 Bad Gateway
