Add support for record classes (data classes) from JDK 14 Feature Preview. https://cr.openjdk.java.net/~briangoetz/amber/datum.html

Right now the out-of-the-box experience while using records in jackson is the following:
Serializing a simple record with no extra methods:

public record TestRecord(int x, int y, int z) {
}

results in a "no properties" exception:
com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class com.company.TestRecord and no properties discovered to create BeanSerializer

A @JsonAutoDetect annotation can be use to solve the problem:

@JsonAutoDetect(fieldVisibility = JsonAutoDetect.Visibility.ANY)
public record TestRecord(int x, int y, int z) {
}

ObjectMapper mapper = new ObjectMapper();
System.out.println(mapper.writeValueAsString(new TestRecord(1, 2, 3)));

results in a correct {"x":1,"y":2,"z":3} output

So right now it works with a little bit of work, but it would be great if there would be a correct out-of-the-box experience with record classes.
