Bug 1762618

Description of problem:

Version-Release number of the following components:
4.3.0-0.nightly-2019-10-16-010826

How reproducible:
Always

Steps to Reproduce:
1. Drop internet gateway for private subnets in VPC to create a disconnected env
2. Set up a proxy in public subnets, the proxy could be connected both external and internal network.
3. In proxy, use whitelist to control which traffic could get through, NOT adding api url into the list. such as:
acl whitelist dstdomain ec2.us-east-2.amazonaws.com iam.amazonaws.com .s3.us-east-2.amazonaws.com .apps.jialiu-42dis8.qe.devcluster.openshift.com ec2-18-191-189-164.us-east-2.compute.amazonaws.com .github.com .rubygems.org 
http_access allow whitelist
4. Enable proxy setting in install-config.yaml
5. Trigger a UPI install on aws

Actual results:
$ ./openshift-install wait-for bootstrap-complete --dir '/home/installer2/workspace/Launch Environment Flexy/workdir/install-dir'
level=info msg="Waiting up to 30m0s for the Kubernetes API at https://api.jialiu-42dis8.qe.devcluster.openshift.com:6443..."
level=info msg="API v1.16.0-beta.2+453eff1 up"
level=info msg="Waiting up to 30m0s for bootstrapping to complete..."
level=info msg="Use the following commands to gather logs from the cluster"
level=info msg="openshift-install gather bootstrap --help"
level=fatal msg="failed to wait for bootstrapping to complete: timed out waiting for the condition"

Expected results:
Installation get passed

Additional info:
Log into bootstrap node, bootkube service is completed successfully.
$ journalctl -b -f -u bootkube.service

The script is calling oc command against external api server to create some resource. But the api server is not in NO_PROXY list.
