Patrick Ohly c4a7fd5cb7 DRA kubelet: adapt to v1alpha3 API 
This adds the ability to select specific requests inside a claim for a
container.

NodePrepareResources is always called, even if the claim is not used by any
container. This could be useful for drivers where that call has some effect
other than injecting CDI device IDs into containers. It also ensures that
drivers can validate configs.

The pod resource API can no longer report a class for each claim because there
is no such 1:1 relationship anymore. Instead, that API reports claim,
API devices (with driver/pool/device as ID) and CDI device IDs. The kubelet
itself doesn't extract that information from the claim. Instead, it relies on
drivers to report this information when the claim gets prepared. This isolates
the kubelet from API changes.

Because of a faulty E2E test, kubelet was told to contact the wrong driver for
a claim. This was not visible in the kubelet log output. Now changes to the
claim info cache are getting logged. While at it, naming of variables and some
existing log output gets harmonized.

Tim Hockin 189da6f245 Set proto go_package: podresources API 
This creates some diff to the *.pb.go files to note that
in the "options".

You can dump the gzipped blob with the following program (thanks
StackOverflow!):

```go
package main

import (
	"bytes"
	"compress/gzip"
	"encoding/json"
	"fmt"
	"os"

	"io/ioutil"

	proto "github.com/golang/protobuf/proto"
	dpb "github.com/golang/protobuf/protoc-gen-go/descriptor"
)

func main() {
	m := map[string][]byte{
		"before": blobv1,
		"after": blobv2,
	}
	arg := os.Args[1]
	dump(m[arg])
}

func dump(bytes []byte) {
	fd, err := decodeFileDesc(bytes)
	if err != nil {
		panic(err)
	}
	b, err := json.MarshalIndent(fd, "", "  ")
	if err != nil {
		panic(err)
	}
	fmt.Println(string(b))
}

// decompress does gzip decompression.
func decompress(b []byte) ([]byte, error) {
	r, err := gzip.NewReader(bytes.NewReader(b))
	if err != nil {
		return nil, fmt.Errorf("bad gzipped descriptor: %v", err)
	}
	out, err := ioutil.ReadAll(r)
	if err != nil {
		return nil, fmt.Errorf("bad gzipped descriptor: %v", err)
	}
	return out, nil
}

func decodeFileDesc(enc []byte) (*dpb.FileDescriptorProto, error) {
	raw, err := decompress(enc)
	if err != nil {
		return nil, fmt.Errorf("failed to decompress enc: %v", err)
	}

	fd := new(dpb.FileDescriptorProto)
	if err := proto.Unmarshal(raw, fd); err != nil {
		return nil, fmt.Errorf("bad descriptor: %v", err)
	}
	return fd, nil
}
```

Tim Hockin 16286abe1c Merge 5 fragile proto-bindings scripts into 1 
Each of these scripts is basically identical, and all were too brittle.
Now they should be more resilient and easier to manage.  The script
still needs to be updated if we add new ones, which I do not love.

More cleanup to follow.
