> ====
> Observed significant performance degradation for volume attach/detach operations and
other storage operations. 
> In the storage operations that were slow, keen observation shows that maximum time was
spent searching for volume on datastore, in that case the attempted storage operation was
volume deletion. The time taken for search was shot up due to large number of empty folder
accumulated over time due to a bug in detach volume logic. We should ensure avoid leaking
empty folder while detaching volume.
