How do you update the workers in the ocp modules.

[lionelmace]

Terraform exposes the attribute [update_all_workers](https://registry.terraform.io/providers/IBM-Cloud/ibm/latest#update_all_workers-1)

How is this field exposed?

@lionelmace We purposely do not expose this in the module because its not a good idea to use terraform to update workers since it will be a disruptive update. Worker updates should be done outside of terraform where best practises are done such as cordoning pods, rolling updates, progressive updates, health checks etc etc
