Evan Lezar 9afe88e41b Add CDI devices to device plugin API 
This change adds CDI device IDs to the ContainerAllocateResponse in the
device plugin API. This allows a device plugin to specify CDI devices
by their unique fully-qualified CDI device names using the related field
in the CRI specification.

Tim Hockin 558a8ec0e0 Set proto go_package: kubelet deviceplugin API 
This exposes that the hand-written code used the wrong package name.

This also 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.

Angus Lees bcb28af0cf Rename deviceIDs -> device_ids to follow protobuf naming conventions 
The protocol buffer [styleguide] says field names should use
underscore_separated_names.

Code generation tools rely on this convention to split words and
generate language-specific accessors/properties in the local style
conventions (ie: it's more than just a style convention).  For
example, the previous `deviceIDs` name caused Rust proto tools to
generate field names like `device_i_ds` which is just weird.

[styleguide]: https://developers.google.com/protocol-buffers/docs/style#message-and-field-names

Rename `deviceIDs` field to `device_ids`, and use a gogo-specific
option to keep the existing `DeviceIDs` golang name (otherwise it
would generate `DeviceIds`).

Note this doesn't affect protocol buffer / gRPC wire encoding, which
uses numeric values.
