Description

From RFC-46:

Extract Record Combining (Merge) API from `HoodieRecordPayload` into a standalone, stateless component – `HoodieRecordCombiningEngine`.

Such component will be
1. Abstracted as stateless object providing API to combine records (according to predefined semantics) for engines (Spark, Flink) of interest
2. Plug-in point for user-defined combination semantics
