CustomConversions should allow for selective registration of default converters [DATACMNS-1349]

[spring-projects-issues]

Mark Paluch opened DATACMNS-1349 and commented

CustomConversions registers default converters (such as Joda-Time, JSR-310, JSR-310 Backport) for all stores. This is behavior is limiting for stores, that come with native support for a type that is currently converted through one of the default converters.

Datastax Cassandra Driver and MongoDB Driver 3.8 come with converters for some JSR-310 types. Leveraging driver support gets Spring Data converters out of the way so drivers are responsible for reading and writing such types.

Ideally, we find an approach that allows selective registration of converters (e.g. CustomConversions accepting a Predicate<ConvertiblePair>)
