What this PR does:
This PR starts the transition moving away from the trace-oriented
max_compaction_objectssetting to a data-orientedmax_block_bytessetting. TimeWindowBlockSelector enforces this limit by simply summing the block data sizes added in #515 which is an estimate but accurate enough. For compatibility,max_compaction_objectsremains as existing blocks may not yet have the new Size, but is deprecated and removed from examples.Additionally, the TimeWindowBlockSelector was refactored to a (hopefully) simpler design that will accommodate more changes to compaction behavior in the future.
Which issue(s) this PR fixes:
