Jackson CsvMapper configuration

[OrangeDog]

Spring Boot currently provides autoconfiguration of Jackson mappers for JSON, CBOR, and XML.

I'm looking to configure add CSV mapping to my application, and it should share the same configuration as the existing three mappers.

The class that does most of the work is AbstractMapperBuilderCustomizer, but that is unfortunately package-private. In lieu of full support from Spring Boot, making that public protected would significantly ease the addition of other Jackson formats.

Hi, I'd like to work on this. I can start by making AbstractMapperBuilderCustomizer public so it can be reused for CsvMapper and other Jackson formats. If the team would also like to add first-class CsvMapper auto-configuration (similar to the existing CborConfiguration / XmlConfiguration), I'm happy to include that as well — let me know which direction you'd prefer. Thanks!

Thanks for the offer, @elephant-y, but this issue is still waiting for triage. As such, it's not ready to be worked on.
