Supports for taint node

[V2arK]

Because default storge class driver for minikube don't support secureContext, I have to use this as a storage class driver for a minikube local dev environment for a project. And to mimic the actual setup on the cloud, taint is used for compute nodes, and this resulted in csi-hostpath-driver not allocating PVCs on compute node at all.

Right now I have to tolerate the taints and make the related daemonset / statefulset / deployment runs only on the tainted node to force the system to allocate PVCs on the tainted node.

Some support for this is needed.

@V2arK If the CSI driver itself is not running on the tainted node, add tolerations to its DaemonSet. Then i think it should work.

You can use

tolerations:
  - key: "compute"
    operator: "Exists"
    effect: "NoSchedule"
