KAFKA-3065: Remove unused topic partitions from RecordAccumulator
Removes unused topic partitions from RecordAccumulator#batches to prevent
the map growing indefinitely. Replaces CopyOnWriteMap with ConcurrentHashMap to
support deletes without double locking. Producer performance tests show no
significant difference.
