> Before CASSANDRA-13215 we used the compaction strategy index to decide which disk to
place a given sstable, but now we can get this directly from the disk boundary manager and
keep the compaction strategy index internal only.
> This will ensure external consumers will use a consistent {{DiskBoundaries}} object to
perform operations on multiple disks, rather than risking getting inconsistent indexes if
the compaction strategy indexes change between successive calls to {{CSM.getCompactionStrategyIndex}}.
