Disabling SMT dynamically inside the image creates problems on AWS.
The problem should be fixed by disabling smt through the VMM.
By recommendation from AWS: add idle=poll.

terraform: collect apiserver cert SANs and support custom endpoint
constants: add new constants for cluster configuration and custom endpoint
cloud: support apiserver cert sans and prepare for endpoint migration on AWS
config: add customEndpoint field
bootstrapper: use per-CSP apiserver cert SANs
cli: route customEndpoint to terraform and add migration for apiserver cert SANs
bootstrapper: change interface of GetLoadBalancerEndpoint to return host and port separately
* deps: downgrade terraform-json to v0.15.0
terraform-exec requires a matching version of terraform json.
Since the latest released version of terraform-exec still uses terraform-json v0.15.0,
we need to stay on that version.
* cli: add "--skip-helm-wait" flag for "constellation init" to "constellation mini up"
* cli: add "--skip-helm-wait" flag
This flag can be used to disable the atomic and wait flags during helm install.
This is useful when debugging a failing constellation init, since the user gains access to
the cluster even when one of the deployments is never in a ready state.
* 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

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.
