[ci:component:github.com/gardener/gardener-extension-provider-azure:v1.22.0->v1.23.1]

[gardener-robot-ci-1]

Release Notes:

Finalizers are now properly added to the `Worker` resource at the start of a `restore` operation.

Azure provider extension now uses non-strict decoder for InfrastructrureStatus resources.

Removed azuremachineclass cleanup logic.

The logic to migrate the Terraform natgateway state will be removed. In case there are `Infrastructure` resources that are created with < `v1.15` and not reconciled with >= `v1.15` they need to be reconciled before a release with this change is applied.

* The node and service controllers now have a configurable sync period (defaults to 4h), so that if an event is missed, the next reconcile will happen at most after this period.
* The node and service predicates now use an expiring cache of nodes / services, so that if an event is missed, the next event is likely to cause a reconcile after comparing with the cache.
* The node and service controllers now also watch "owned" `VirtualMachine` and `PublicIPAddress` resources and would trigger a reconcile if a an unexpected situation is detected, such as creating or updating an object without an owner, deleting an object with an owner that is not being deleted, etc.
* The node and service controllers have been enhanced to ensure that any owned objects are deleted if the node or service is not found.
* The service controller has been enhanced to also delete any still existing "owned" `PublicIPAddress` resources that are not found in the service `LoadBalancer` IPs when deleting a service or ensuring that it's deleted.

End User can now delete the backing machine object of the node instantly by annotating the desired node with  'node.machine.sapcloud.io/trigger-deletion-by-mcm="true"`

Operators can now provide a list of service principals that can be used in case the user does not provide service principal information in the secret for her/his Shoot.

A bug has been fixed in the pre-delivered CRD manifests for MCM (`/kubernetes/crds`). It caused data to be pruned from MCM related resources and led to reconciliation issues.

Update Kubernetes dependency versions to v1.20.6
