Description

In CompactionTask#buildCompactionCandidatesForAvailableDiskSpace with LCS, if node has limited disk space and can't remove any sstable from L0 or L1 in LeveledCompactionTask#reduceScopeForLimitedSpace, LeveledCompactionTask#partialCompactionsAcceptable will throw UnsupportedOperationException.

We should handle LeveledCompactionTask#partialCompactionsAcceptable more gracefully with return level <= 1 or simply true since reduceScopeForLimitedSpace only removes sstable from L0 or L1.
