Add a script to remove all the resources deployed as the part of CSI Driver

- added a version specific destroy script parallel to deploy-script

- added labels to all the resources of csi deployment along with the podSpec template label-selector

- added labels to rbac files on the fly locally in /tmp/* folder to be able to track using kustomize

- cleanup gitignore

- Useful to cleanup the resources which can interfere with the redeployments or on some automations based
on the Driver deployment
