  * Avoid spurious ELB listener recreation - ignore case when matching protocol ([#47391](https://github.com/kubernetes/kubernetes/pull/47391), [@justinsb](https://github.com/justinsb))

    *  - vSphere cloud provider (VCP) uses OS hostname and not vSphere Inventory VM Name.
    *    That means, now  VCP can handle cases where user changes VM inventory name.
    * - VCP can handle cases where VM migrates to other ESXi cluster or datacenter or vCenter.
    * The only requirement is the shared storage. VCP needs shared storage on all Node VMs.

ServiceCheck for the `docker` service from kubeadm preflight. Docker is no longer special cased during host validation and ideally this task should be done in the now external cri-dockerd project where the importance of the compatibility matters. Use `crictl` for all communication with CRI sockets for actions like pulling images and obtaining a list of running containers instead of using the docker CLI in the case of Docker.

- Previously, the scheduling queue didn't notice any extenders' failures, potentially resulting in missed cluster events and Pods rejected by Extenders being stuck in the unschedulable pod pool for up to 5 minutes in the worst-case scenario. Now, the scheduling queue notices extenders' failures and requeues Pods rejected by Extenders appropriately.
