Add 'cluster-autoscaler.kubernetes.io/safe-to-evict: true' annotation to all pods.

Clusters are now running with Cluster Autoscaler turned on which automatically resizes the Node Pools.

  https://cloud.google.com/kubernetes-engine/docs/concepts/cluster-autoscaler

That means that every pod should have the following annotation:

```yaml
annotations:
  cluster-autoscaler.kubernetes.io/safe-to-evict: 'true'
```

If you need finer grained control over how your pods are started and stopped that can be done by defining a PodDisruptionBudget.

   https://kubernetes.io/docs/concepts/workloads/pods/disruptions/

CockroachDB defines a PodDisruptionBudget and is a good example of such a budget.
