1. Support row-level CDC records generation and persistence;
2. Support both MOR and COW tables;
3. Support all the write operations;
4. Support Spark DataFrame/SQL/Streaming Query;

switch of the CDC features. If `true`, writers and readers will respect CDC
configurations and behave accordingly. |

persist the required information about the changed data, including `before`. If
`false`, only `op` and record keys will be persisted. |

persist `after` as well.

Review Comment:
i think one config `hoodie.table.cdc.supplemental.logging` maybe is enough.
Less configs will improve the ease of use. If not,
`hoodie.table.cdc.supplemental.logging.include_before` will be needed to
provide.
