The io/ioutil package has been deprecated as of Go 1.16 [1]. This commit
replaces the existing io/ioutil functions with their new definitions in
io and os packages.

* Use container image name in server as-is
Don't rename it to disk.img, in order to support restricted security
context where image uid:gid don't allow renaming it. E.g. DV/DIC with
the following results image named downloaded with 107:107:
```
source:
registry:
pullMethod: node
url: docker://quay.io/kubevirt/cirros-container-disk-demo
```

* Support registry import using node docker cache
The new CRI (container runtime interface) importer pod is created with three containers and a shared emptyDir volume:
-Init container: copies static http server binary to empty dir
-Server container: container image container configured to run the http binary and serve up the image file in /data
-Client container: import.sh uses cdi-import to import from server container, and writes "done" file on emptydir
-Server container sees "done" file and exits
Thanks mhenriks for the PoC!
Done:
-added ImportMethod to DataVolumeSourceRegistry (DataVolume.Spec.Source.Registry, DataImportCron.Spec.Source.Registry).
Import method can be "skopeo" (default), or "cri" for container runtime interface based import
-added cdi-containerimage-server & import.sh to the cdi-importer container
ToDo:
-utests and func tests
-doc
