[machine-controller-manager]

⚠️ Breaking Changes

• [OPERATOR] Removal of the following flags (and corresponding fields in associated structs): 'machine-creation-timeout' 'machine-drain-timeout', 'machine-pv-detach-timeout', 'machine-health-timeout=10m', 'machine-safety-apiserver-statuscheck-timeout', 'machine-safety-apiserver-statuscheck-period', 'machine-safety-orphan-vms-period', 'machine-max-evict-retries', 'node-conditions', 'bootstrap-token-auth-extra-groups', 'delete-migrated-machine-class'. The MCM no longer accepts these flags since these are options handled by the Machine Controller invoked by platform specific provider launchers. (gardener/machine-controller-manager#769, @elankath)
• [DEVELOPER] Deletion of 'Driver.GenerateMachineClassForMigration'. Providers need to adapt to this. (gardener/machine-controller-manager#769, @elankath)

• [USER] An edge case where all the machineSets were scaled down to zero has been dealt with. (gardener/machine-controller-manager#804, @himanshu-kun)
• [USER] An edge case where outdated DesiredReplicas annotation blocked a rolling update is fixed. (gardener/machine-controller-manager#822, @rishabh-11)
• [OPERATOR] An issue causing nil pointer panic on scaleup of the machinedeployment along with trigger of rolling update, is fixed (gardener/machine-controller-manager#817, @himanshu-kun)
