kubermatic/machine-controller v1.57.0 on GitHub

The default values for webhook flags tls-cert-path and tls-key-path have been changed to /tmp/cert/tls.crt and /tmp/cert/tls.key respectively. This is a result of updating it to use certificates generated from cert-manager (#1644)
Deprecation: User data plugins for machine-controller are deprecated and will soon be removed. Operating System Manager is the successor of user data plugins.
