It improves (or fixes) the `workers.safeToEvict` usage.
Kubernetes administrators/users agree that
`cluster-autoscaler.kubernetes.io/safe-to-evict` can be managed to avoid the
Autoscaler to kill the worker pod when scaling nodes down.
> When this annotation is set to "true", the cluster autoscaler is allowed
to evict a Pod even if other rules would normally prevent that. The cluster
autoscaler never evicts Pods that have this annotation explicitly set to
"false"; you could set that on an important Pod that you want to keep running.
If this annotation is not set then the cluster autoscaler follows its Pod-level
behavior.
So, if I set `workers.safeToEvict` to `false`, it gets nothing. The
Autoscaler will kill that still. Because the Helm chart has no effect on
handling that. See:
```
{{- if .Values.workers.safeToEvict }}
cluster-autoscaler.kubernetes.io/safe-to-evict: "true"
{{- end }}
```
It's like a useless piece of statement.
What about if I need to set that to false? I couldn't. Anybody is unable to.
A probaly **workaround** would set up `workers.podAnnotations` with map of
_annotations_ and `workers.safeToEvict` falsely together.
Please, check it out carefully. Thanks in advance!
