Not generate bson:"_id, omitempty"

[bingochen87]

Use example code to regenerate data.pb.go, but not generate bson:"_id, omitempty" or other tag "bson:xxxxx" fields.

Code fragment:

package main

import (
	fmt "fmt"
	pmongo "github.com/amsokol/mongo-go-driver-protobuf/pmongo"
	_ "github.com/amsokol/protoc-gen-gotag/tagger"
	proto "github.com/golang/protobuf/proto"
	timestamp "github.com/golang/protobuf/ptypes/timestamp"
	wrappers "github.com/golang/protobuf/ptypes/wrappers"
	math "math"
)

// Reference imports to suppress errors if they are not otherwise used.
var _ = proto.Marshal
var _ = fmt.Errorf
var _ = math.Inf

// This is a compile-time assertion to ensure that this generated file
// is compatible with the proto package it is being compiled against.
// A compilation error at this line likely means your copy of the
// proto package needs to be updated.
const _ = proto.ProtoPackageIsVersion3 // please upgrade the proto package

Sorry for that, I don't use the second command.
