Expose hugepage requests to container via Downward API
In Kubernetes 1.20, an alpha feature was added to expose the requested hugepages to the container via the Downward API. This is feature is disabled by default. If enabled when Kubernetes is deployed via FEATURE_GATES="DownwardAPIHugePages=true", then Network Resource Injector can be used to mutate the pod spec to publish the hugepage data to the container. Since the Kubernetes feature is disabled by default, added a configuration parameter to turn on the Network Resource Injector code.
