The patch that removes DatabaseDescriptor dependency and {{ChunkCache}} singleton access from
{{SegmentedFile}}.
- All subclasses of {{SegmentedFile}} are merged into {{SegmentedFile}} since difference among
those is in {{Rebufferer}} after CASSANDRA-5863.
- Introduced {{DiskOptimizationStrategy}} for {{disk_optimization_strategy}} config.
- {{SegmentedFile.Builder}}'s {{serializeBound}}/{{deserializedBound}} seem no longer used,
so I removed them.
