---------------------------------------------------------------------
Inline deletion of multilevel nodes in snapshotSkipList is quite fast.
Moreover, async deletion of multilevel nodes from snapshotSkipList containing
snapshotDiffs leads to complicated scenarios of maintaining quota consistency
semantics in HDFS. It won't be done for now.
