Update client-go to v10.0.0 (Kubernetes 1.13) (#2382)

* Update client-go to v10.0.0 (Kubernetes 1.13)

This fix updates client-go to v10.0.0 which matches
Kubernetes 1.13 (released several days ago).

Other changes in Gopkg.yaml:
- Updated apimachinary, api, klog, yaml associated with k8s version
  go dep will not automatically match the version.
- Added [prune] field (otherwise go dep will not prune automatically)

-* concurrent.Map: backport sync.Map for go below 1.9
-* concurrent.Executor: goroutine with explicit ownership and cancellable
-
-# concurrent.Map
-
-because sync.Map is only available in go 1.9, we can use concurrent.Map to make code portable
-
-```go
-m := concurrent.NewMap()
-m.Store("hello", "world")
-elem, found := m.Load("hello")
-// elem will be "world"
-// found will be true
-```
-
-# concurrent.Executor
-
-```go
-executor := concurrent.NewUnboundedExecutor()
-executor.Go(func(ctx context.Context) {
-    everyMillisecond := time.NewTicker(time.Millisecond)
-    for {
-        select {
-        case <-ctx.Done():
-            fmt.Println("goroutine exited")
-            return
-        case <-everyMillisecond.C:
-            // do something
-        }
-    }
-})
-time.Sleep(time.Second)
-executor.StopAndWaitForever()
-fmt.Println("executor stopped")
-```
-
-attach goroutine to executor instance, so that we can
-
-* cancel it by stop the executor with Stop/StopAndWait/StopAndWaitForever
-* handle panic by callback: the default behavior will no longer crash your application
