Automatically add 168.63.129.16 IP to noProxy in Azure Stack Hub

Version:

$ openshift-install version
4.10.20

Platform:

Azure Stack Hub

Please specify:
IPI (automated install with `openshift-install`. If you don't know, then it's IPI)

What happened?

When proxy server is in place and http(s)Proxy+noProxy is added to isntall-config.yaml. After manifests are generated additional proxy setting should be auto-appended to proxy configuration .yaml

1. Azure VIP 168.63.129.16
See -> https://docs.microsoft.com/en-us/azure/virtual-network/what-is-ip-address-168-63-129-16

this needs to be noProxy to let a VM report back about it's creation status

2. armEndpoint of ASH - to make sure that future cluster nodes do not communicate with a Stack Hub API through proxy

What did you expect to happen?

Expected these two be auto-added as they are very specific and difficult to troubleshoot

How to reproduce it (as minimally and precisely as possible)?

Need to have a proxy server in ASH and rung the installer
