Issues starting with custom metrics API server

Initialization

$ cd $GOPATH/src/github.com/trstringer
$ mkdir testing01
$ cd testing01
$ dep init
$ touch main.go

Then in main.go:

package main

import (
	"fmt"
	basecmd "github.com/kubernetes-incubator/custom-metrics-apiserver/pkg/cmd"
)

func main() {
	fmt.Println("Hello world")
}

Then back in the terminal in the working directory of the project:

 $ dep ensure -v
# Gopkg.lock is out of sync with Gopkg.toml and project imports:
github.com/kubernetes-incubator/custom-metrics-apiserver/pkg/cmd: imported or required, but missing from Gopkg.lock's input-imports
