Fix For: 4.9.1.0
Issue
====
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.
