- Adds profile label to kube-scheduler metric schedule_attempts_total

  Example: suppose you develop a custom plugin that denies Pods that have a `schedulable=false` label.

`istioctl kube-inject` or the automatic sidecar injector are used to select the environment.
In the case of the sidecar injector, the namespace label `istio-env: <NAME_OF_ENV>` is used instead
of the conventional `istio-injected: true`. The name of the environment is defined as the namespace

        "More data is available.",
        "Access is denied.",
        "The data area passed to a system call is too small.",
        "The filename, directory name, or volume label syntax is incorrect.",
        "The system cannot find the file specified.",
        "Cannot create a file when that file already exists.",
        "The handle is invalid.",
        "The specified path is invalid.",

- Transformation_operations_total metric will have additional resource label which can be used for resource specific validations for example handling of encryption config by the apiserver.

- Kubelet should reconcile `kubernetes.io/os` and `kubernetes.io/arch` labels on the node object. The side-effect of this is kubelet would deny admission to pod which has nodeSelector with label `kubernetes.io/os` or `kubernetes.io/arch` which doesn't match the underlying OS or arch on the host OS. 

	return "Remote already exists for this bucket: " + e.Bucket
}

// BucketRemoteLabelInUse remote already exists for this target label.
type BucketRemoteLabelInUse GenericError

func (e BucketRemoteLabelInUse) Error() string {
	return "Remote with this label already exists for this bucket: " + e.Bucket
}

// BucketRemoteArnTypeInvalid arn type for remote is not valid.

  pre-1.0 to 1.6 kubelet is not supported.
* Fluentd was migrated to Daemon Set, which targets nodes with
  beta.kubernetes.io/fluentd-ds-ready=true label. If you use fluentd in your
  cluster please make sure that the nodes with version 1.6+ contains this
  label.

### kubectl
* Running `kubectl taint` (alpha in 1.5) against a 1.6 server requires upgrading kubectl to version 1.6
