Issue with accessing an application in a proxy setup with libvirt provider.

[LalatenduMohanty]

We are getting below error after an application gets deployed in OpenShift running in ADB in a http proxy environment.

curl: (6) Could not resolve host: cakephp-example-sample-project.centos7-adb.10.1.2.2.xip.io; Unknown error

Steps to reproduce

1. Add proxy setup in OpenShift Vagrantfile [1] as mentioned below.
2. Do oc login
3. Deploy an application e.g. oc new-app nodejs-example
4. Once the application is deployed oc status run oc get route
5. Try to access the application.
