Upgrade SR-IOV provider nodes image to k8s-1.22

The new KinD k8s-1.22 nodes includes a change [1] [2] that allows us
to stop using PodPresets and still support Kubevirt Live Migration.

+# K8S 1.22.2 with SR-IOV in a Kind cluster
+
+Provides a pre-deployed containerized k8s cluster with version 1.22.2 that runs
+using [KinD](https://github.com/kubernetes-sigs/kind)
+The cluster is completely ephemeral and is recreated on every cluster restart. The KubeVirt containers are built on the
+local machine and are then pushed to a registry which is exposed at
+`localhost:5000`.
+
+This version also expects to have SR-IOV enabled nics (SR-IOV Physical Function) on the current host, and will move
+physical interfaces into the `KinD`'s cluster worker node(s) so that they can be used through multus and SR-IOV
+components.
+
+This providers also deploys [multus](https://github.com/k8snetworkplumbingwg/multus-cni)
+, [sriov-cni](https://github.com/k8snetworkplumbingwg/sriov-cni)
+and [sriov-device-plugin](https://github.com/k8snetworkplumbingwg/sriov-network-device-plugin).
+
+## Bringing the cluster up
+
+```bash
+export KUBEVIRT_PROVIDER=kind-1.22-sriov
+export KUBEVIRT_NUM_NODES=3
+make cluster-up
+
+$ cluster-up/kubectl.sh get nodes

+kube-sriov-device-plugin-amd64-xrr5z   1/1     Running   0          20h
+```
+
+## Bringing the cluster down
+
+```bash
+export KUBEVIRT_PROVIDER=kind-1.22-sriov
+make cluster-down
+```
+
+This destroys the whole cluster, and moves the SR-IOV nics to the root network namespace.
+
+## Setting a custom kind version
+
+In order to use a custom kind image / kind version, export `KIND_NODE_IMAGE`, `KIND_VERSION`, `KUBECTL_PATH` before
+running cluster-up. For example in order to use kind 0.9.0 (which is based on k8s-1.19.1) use:
+
+```bash
+export KIND_NODE_IMAGE="kindest/node:v1.19.1@sha256:98cf5288864662e37115e362b23e4369c8c4a408f99cbc06e58ac30ddc721600"
+export KIND_VERSION="0.9.0"
+export KUBECTL_PATH="/usr/bin/kubectl"
+```
+
+This allows users to test or use custom images / different kind versions before making them official.
+See https://github.com/kubernetes-sigs/kind/releases for details about node images according to the kind version.
+
+## Running multi SR-IOV clusters locally
+
+Kubevirtci SR-IOV provider supports running two clusters side by side with few known limitations.
+
+General considerations:
+
+- A SR-IOV PF must be available for each cluster. In order to achieve that, there are two options:
+
+1. Assign just one PF for each worker node of each cluster by using `export PF_COUNT_PER_NODE=1` (this is the default
+   value).
+2. Optional method: `export PF_BLACKLIST=<PF names>` the non used PFs, in order to prevent them from being allocated to
+   the current cluster. The user can list the PFs that should not be allocated to the current cluster, keeping in mind
+   that at least one (or 2 in case of migration), should not be listed, so they would be allocated for the current
+   cluster. Note: another reason to blacklist a PF, is in case its has a defect or should be kept for other operations (
+   for example sniffing).
+
+- Clusters should be created one by another and not in parallel (to avoid races over SR-IOV PF's).
+- The cluster names must be different. This can be achieved by setting `export CLUSTER_NAME=sriov2` on the 2nd cluster.
+  The default `CLUSTER_NAME` is `sriov`. The 2nd cluster registry would be exposed at `localhost:5001` automatically,
+  once the `CLUSTER_NAME`
+  is set to a non default value.
+- Each cluster should be created on its own git clone folder, i.e:
+  `/root/project/kubevirtci1`
+  `/root/project/kubevirtci2`
+  In order to switch between them, change dir to that folder and set the env variables `KUBECONFIG`
+  and `KUBEVIRT_PROVIDER`.
+- In case only one PF exists, for example if running on prow which will assign only one PF per job in its own DinD,
+  Kubevirtci is agnostic and nothing needs to be done, since all conditions above are met.
+- Upper limit of the number of clusters that can be run on the same time equals number of PFs / number of PFs per
+  cluster, therefore, in case there is only one PF, only one cluster can be created. Locally the actual limit currently
+  supported is two clusters.
+- In order to use `make cluster-down` please make sure the right `CLUSTER_NAME` is exported.
