Support for ReadWriteOncePod

[3deep5me]

What would you like to be added:
It would be great if the kindest local-path-provisioner would support ReadWriteOncePod.
It seems like it's already implemented here rancher/local-path-provisioner#331

Why is this needed:
I love to use kind for training and demo purposes and i would like to show/demo the accessMode "ReadWriteOncePod" with kind.

AccessMode ReadWriteOncePod is imported when you do not want that pods share the same Volume - this is the case with ReadWriteOnce. https://kubernetes.io/docs/concepts/storage/persistent-volumes/#access-modes

v0.0.30 is available in kind v0.26.0 but I haven't checked if this works yet and it's possible we'd use another provisioner in the future 😅

Yeah nice! It seems like to work with the current version. Thank you!
