Mirroring the various YAML files by hand is tedious. The new
update-hostpath.sh does all the necessary steps automatically.
The result is now a bit more consistent with the upstream repos in the
sense that the original file names and paths for the RBAC YAML files
are used.
The csi-hostpath-testing.yaml is included for the sake of
completeness, but not used during E2E testing.
The new hostpath driver release is v1.6.2, which adds the
external-health-monitor for the first time.
