feat(rancher-vsphere-cpi): add labels option to vCenter

[secustor]

Pull Request Checklist

• Any new images or tags consumed by charts has been added here
• That helm lint and pack run successfully on the chart.
• Deployment of the chart has been tested and verified that it functions as expected.
• Changes to scripting or CI config have been tested to the best of your ability

Types of Change

• added the labels configuration to vsphere.conf. This allows to propagate regions and availability zones to nodes and the vSphere CSI
• use YAML instead of INI as this is recommended as of v1.2.0

Additional Notes

https://cloud-provider-vsphere.sigs.k8s.io/tutorials/kubernetes-on-vsphere-with-kubeadm.html

NOTE: As of CPI version 1.2.0 or higher, the preferred cloud-config format will be YAML based. The INI based format will be deprecated but supported until the transition to the preferred YAML based configuration has been completed. This deprecation notice will be placed in the CPI logs when using the INI based configuration format.
