Ability to configure kube-scheduler under ClusterConfig.scheduler

[cvandesande]

Feature Request

kube-scheduler can be configured with a PodTopologySpread yaml configuration file (example attached). The Kubernetes reference mentions the config yaml should be passed to the kube-scheduler command with the --config path/to/yaml option. See here.

I believe this can be achieved in Talos with a combination of extraArgs and extraMounts but it's not the most intuitive approach. It would be nice if Talos supported inline configuration directly in cluster.scheduler kube-scheduler-topology.yaml.txt

Thanks again for this amazing project.
