-------------------------------------

[~nfilotto] if you get some time and want to work on a bit of Camel then here is a nice improvement in the fluent builder you added.

> See this class JsonPathSplitSingleListOptionTest
>                 var jsonpath = expression().jsonpath().option(Option.ALWAYS_RETURN_LIST.name()).expression("$.store.book[0]").end();
> The option is an enum from camel-jsonpath, but the DSL method accepts only a String. It would be nice if we could somehow pass in just the enum field, without having to call .name(), ala:
>                 var jsonpath = expression().jsonpath().option(Option.ALWAYS_RETURN_LIST).expression("$.store.book[0]").end();
> So we have both a String and an enum field method in the generated fluent builder.
