This test creates a pod with custom DNS configurations and expects
them to be set in the containers.
The test pod is using the agnhost image, which can output the container's
DNS configurations that the test checks.
At the moment, Windows cannot mount individual files into Containers, which means
that the Kubelet-managed hosts file cannot be mounted into the Container, causing
the "should provide DNS for pods for Hostname and Subdomain" test to fail.
The mentioned test has /etc/hosts file entry checks. This commits separates the
DNS check and the /etc/hosts checks into two tests.
Windows containers do not include a route to the GCE metadata server by
default. This check is causing the "DNS should provide DNS for the
cluster" test to fail for clusters with Windows nodes
(https://testgrid.k8s.io/sig-windows#gce-windows-master&width=20).
Tested that this works by running "DNS should provide DNS for the
cluster" against an e2e cluster with Windows nodes brought up on GCE.
At the moment, Windows cannot mount individual files into Containers, which means
that the Kubelet-managed hosts file cannot be mounted into the Container, causing
the "should provide DNS for the cluster" test to fail.
This test separates the hosts entries checks from the mentioned test to a new test.

This PR adds pod related conformance annotations to the e2e test suite.
The PR fixes a portion of #53822. It focuses on adding conformance annotations as defined by the Kubernetes Conformance Workgroup for a subset of the dns, configmap, and custom resource definition based e2e conformance tests.
