Proposed title of this feature request:

Allow overwrite of Share host ip

What is the nature and description of the request?

My customer wants to change the share host ip to a haproxy that forwards traffic to the master nodes.
Out-of-Band(OOB) subnet: 10.118.145.64/26
Openshift machine cidr: 10.123.0.128/26
Haproxy ip: 10.118.17.70

Traffic cannot go directly from OOB to Machine cidr which is default configured when using virtualmedia mount.
So they have an haproxy configured that forward traffic to the master nodes. They can mount the image by hand when they point the share host ip to the haproxy but they cannot find any configuration to make openshift configure this ip automatically.

OOB -> Haproxy(10.118.17.70) -> Master nodes (master-2: 10.123.0.181)

Why does the customer need this? (List the business requirements here)

Due to the way the network is configured the OOB cannot connect to the nodes so they need a way to proxy this.

List any affected packages or components.
