* helm: configure GCP cloud controller manager to search in all zones of a region
See also: d716fdd452/providers/gce/gce.go (L376-L380)
* operators: add nodeGroupName to ScalingGroup CRD
NodeGroupName is the human friendly name of the node group that will be exposed to customers via the Constellation config in the future.
* operators: support simple executor / scheduler to reconcile on non-k8s resources
* operators: add new return type for ListScalingGroups to support arbitrary node groups
* operators: ListScalingGroups should return additionally created node groups on AWS
* operators: ListScalingGroups should return additionally created node groups on Azure
* operators: ListScalingGroups should return additionally created node groups on GCP
* operators: ListScalingGroups should return additionally created node groups on unsupported CSPs
* operators: implement external scaling group reconciler
This controller scans the cloud provider infrastructure and changes k8s resources accordingly.
It creates ScaleSet resources when new node groups are created and deletes them if the node groups are removed.
* operators: no longer create scale sets when the operator starts
In the future, scale sets are created dynamically.
* operators: watch for node join/leave events using a controller
* operators: deploy new controllers
* docs: update auto scaling documentation with support for node groups
* init
* make zone flag mandatory again
* add info about zone update + refactor
* add comment in docs about zone update
* Update cli/internal/cmd/iamcreate_test.go

This change is required to ensure we have not tls handshake errors when connecting to the kubernetes api.
Currently, the certificates used by kube-apiserver pods contain a SAN field with the (single) public ip of the loadbalancer.
If we would allow multiple loadbalancer frontend ips, we could encounter cases where the certificate is only valid for one public ip,
while we try to connect to a different ip.
To prevent this, we consciously disable support for the multi-zone loadbalancer frontend on AWS for now.
This will be re-enabled in the future.
* Fix usage of errors.As in upgrade command implementation
* Use struct pointers when working with custom errors

Normalize naming for the "instance_count" / "initial_count" int terraform to always use "initial_count".
This is required, since there is a naming confusion on AWS.
"initial_count" is more precise, since it reflects the fact that this value is ignored when applying the terraform template
after the scaling groups already exist.
This commit is designed to be reverted in the future (AB#3248).
Terraform does not implement moved blocks with dynamic targets: https://github.com/hashicorp/terraform/issues/31335 so we have to migrate the terraform state ourselves.
