Drop asyncJavaPaginatedRequest

[vigoo]

Drop asyncJavaPaginatedRequest if possible and use asyncSimplePaginatedRequest instead. This would make all pagination unified and run the aspects for each pagination call not just the top level one.

Note that it is not enough to simply just remove the support for the Java paginated requests, the native has to be improved to not only support the NextToken interface but custom ones defined in the paginator schema too, as for example query in https://github.com/aws/aws-sdk-java-v2/blob/master/services/dynamodb/src/main/resources/codegen-resources/dynamodb/paginators-1.json
