What this PR does / why we need it:
This PR adds support to concurrently upgrade MachineDeployments in Classy Clusters.
The maximum concurrency is defined by setting the
topology.cluster.x-k8s.io/upgrade-concurrencyannotation on the Cluster. If unspecified a default concurrency of 1 is used (only one MachineDeployment is upgraded at a time).Example: If the annotation
"topology.cluster.x-k8s.io/upgrade-concurrency": "3"is set on the Cluster at most 3 MachineDeployments will be upgraded concurrently.This upgrade concurrency honors the
topology.cluster.x-k8s.io/defer-upgradeandtopology.cluster.x-k8s.io/hold-upgrade-sequenceannotations applied on the MachineDeploymentTopology and upgrades the qualifying MachineDeployments concurrently.Which issue(s) this PR fixes (optional, in
fixes #<issue number>(, fixes #<issue_number>, ...)format, will close the issue(s) when PR gets merged):Fixes #
