The CSI spec requires the CO (= csi-sanity) to create the staging
directory and the parent of the target
directory. Kubernetes (kubernetes/kubernetes#75535)
and csi-sanit have handled the target directory incorrectly by
creating it.
Now directory handling is standard-compliant and more strict, to catch
mistakes:
created by csi-sanity, while the actual NodePublishVolume call then
specifies an entry inside that directory; this was done to keep the
code simple (handling both directories is the same) and to minimize
API changes
os.MkdirAll and os.RemoveAll; as a result, both directories
now must be different (which is what they should have been in the
anyway, it just happened to work when they were identical)
