Reduce scope of default tolerations

[wongma7]

/kind bug

What happened? Exists is too much, we should tone it down in next helm chart release: kubernetes-sigs/aws-ebs-csi-driver#758 (comment)

What you expected to happen?

How to reproduce it (as minimally and precisely as possible)?

Anything else we need to know?:

Environment

• Kubernetes version (use kubectl version):
• Driver version:

This is a major issue that prevents the EFS CSI pods from being evicted when a node is scaled down by the Kubernetes cluster-autoscaler.

Allowing the pod to tolerate all taints seems to be in direct opposition to the way NotReady and NoExecute taints are designed in Kubernetes and effects the operation of other Kubernetes system pods.

It looks like the default toleration was removed from controller-deployment.yaml as part of release v1.3.1 - this issue can likely be closed.

yes it should be fixed by latest driver + helm chart
