[ci:component:github.com/gardener/machine-controller-manager:v0.46.0->v0.48.2]

[gardener-robot-ci-2]

Release Notes:

resourceName `machine-controller` added for leases in clusterrole. Updated version of Clusterroles and Clusterrolebindings to v1.

An edge case where all the machineSets were scaled down to zero has been dealt with.

Bootstrap token replacement by MCM is now supported for Ignition userData format

Migrated clients to use `policy/v1` `PodDisruptionBudget` for kubernetes versions >= 1.21. `policy/v1beta1` PDB is also supported but for k8s < 1.21

Fix a bug in the bootstrap token creation that caused node to not be able to join the cluster due to an expired bootstrap token.

`node` field is removed from machine status. controller will now depend on the node label which already was present in the machine object's metadata. If you(or your controller) are dependent on the `status.node` field of the machine object, then kindly use `node` label under `.metadata.labels`

Added new short names for machine(mc), machineClass(mcc), machineDeployment(mcd), and machineSet(mcs) resources.

Using `kubectl get machines` will display `Node` of the corresponding machine as a column. If `-owide` flag is used then the corresponding `ProviderID` will also be displayed.

Updated golang version to v1.19.2

MachineDeployment would now have `Progressing` condition even when no progress Deadline is specified. This condition would never go to the reason `ProgressDeadlineExceeded` in that case.

If during a rolling update scale-up is done, MCM scales up only the new machineSet, while in case of scale-down the scale-down amount is split among old machineSets, in proportion to their sizes.

go version updated to 1.19.4 in pipeline and Dockerfile
