ci: create kubernetes cluster with `none` VM driver

We are now creating a kubernetes cluster with KVM as VM driver, This will create a virtual machine with minikube.iso and install kubernetes inside the virtual machine. we have disadvantages like
* We might not able to utilize all the resources of the host machine
* We need to depend on the kernel that comes with the minikube virtual machines
* This is blocking us from testing the features like new rbd image features, nbd driver, etc.

As we get new worker nodes for each job we run in centos CI we are good to use the host to run the kubernetes cluster.
