Create fake /etc/hosts for conformance test **What this PR does / why we need it**: "KubeletManagedEtcHosts should test kubelet managed /etc/hosts file" conformance test fails in the CI's Docker-In-Docker environment. This test mounts a /etc/hosts file and checks if "# Kubernetes-managed hosts file." string is present or not under various conditions. The specific failure with DIND happens when the /etc/hosts picked up from the box where e2e test are running already has this string. This happens because our CI runs on kubernetes and the e2e tests are running in a container that was started on kubernetes (and hence already has that string) To avoid this situation, we create a new /etc/hosts file with known contents (and does not have the "# Kubernetes-managed hosts file." string) **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: Fixes # **Special notes for your reviewer**: Please see: https://k8s-testgrid.appspot.com/sig-testing-misc#ci-kubernetes-local-e2e https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/logs/ci-kubernetes-local-e2e/285 **Release note**: ```release-note NONE ```
