[BUG] java-vertx-web uses internal HttpStatusException vertx class

The vertx generator is using io.vertx.ext.web.handler.impl.HttpStatusException in each method default implementation.

example:

import io.vertx.ext.web.handler.impl.HttpStatusException;

import java.util.List;
import java.util.Map;

// Implement this class

public class BusinessApiImpl implements BusinessApi {
    public Future<ApiResponse<Void>> deleteCompanyId(String q, Integer id) {
        return Future.failedFuture(new HttpStatusException(501));
    }

This class was internal: Since vertx 4.1 this class is part of vertx official API and has changed to io.vertx.ext.web.handler.HttpException, code generated with java-vertx-web is uncompilable in the stable vertx versions.

Locate the java-vertx-web generator template that emits the default method implementation and search for HttpStatusException references. Update the generated output to use the stable Vert.x HttpException API, then verify that generated Java compiles against stable Vert.x versions.
