e2e storage: synchronize .yaml files with latest upstream releases

This ensures that the files are in sync with:
   hostpath: v1.2.0-rc3
   external-attacher: v2.0.1
   external-provisioner: v1.3.0
   external-resizer: v0.2.0
   external-snapshotter: v1.2.0

driver-registrar/rbac.yaml is obsolete because only
node-driver-registrar is in use now and does not need RBAC rules.

mock/e2e-test-rbac.yaml was not used anywhere.

The README.md files were updated to indicate that these really are
files copied from elsewhere. To avoid the need to constantly edit
these files on each update, <version> is used as placeholder in the URL.
