test/e2e/storage: replace mock driver with hostpath driver

This is a first step towards removing the mock CSI driver completely from
e2e testing in favor of hostpath plugin. With the recent hostpath plugin
changes(PR #260, #269), it supports all the features supported by the mock
csi driver.

Using hostpath-plugin for testing also covers CSI persistent feature
usecases.
