set up a bastion host as proxy server, then trigger the installation would tell failing to wait for the Kubernetes API, although the installation succeeds finally by itself

    see the build https://prow.ci.openshift.org/view/gs/test-platform-results/logs/release-openshift-origin-installer-launch-aws-modern/1910510784354455552

    Always

1. create VPC network/subnets/etc.  (see [1])
2. create bastion host within the VPC, which will act as http proxy server (see [2])
3. "create install-config", then insert the interested settings (see [3])
4. export http_proxy & https_proxy settings (see [4])
5. "create cluster" (see [5])

Failed on waiting for the Kubernetes API with below error, please note that the IP "34.8.255.171" is the API server's IP, rather than the bastion host's IP.

ERROR Attempted to gather ClusterOperator status after installation failure: listing ClusterOperator objects: Get "https://api.jiwei-0411z.qe.gcp.devcluster.openshift.com:6443/apis/config.openshift.io/v1/clusteroperators": proxyconnect tcp: dial tcp 34.8.255.171:3128: i/o timeout 

    Installer should not take API server as the proxy server, and tell successful installation.
