Out-of-the-box support for generation with DataObject-annotation

[jklingsporn]

It is not very userfriendly to create the POJOs with DataObject-annotation:

• create a new maven module with a dependency to vertx-jooq-generate
• create a new class that extends DelegatingVertxGenerator like this

public class ClassicReactiveVertxGeneratorWithDataObjectSupport extends DelegatingVertxGenerator {

    public ClassicReactiveVertxGeneratorWithDataObjectSupport() {
        super(VertxGeneratorBuilder.init().withClassicAPI().withPostgresReactiveDriver().build(new BuildOptions().withBuildFlags(EnumSet.of(BuildOptions.BuildFlag.GENERATE_DATA_OBJECT_ANNOTATION))));
    }
}

• build the module
• reference the new generator in your gradle plugin configuration
• note: the generated classes require a dependency to the vertx-codegen-module so make sure to add that to your dependency-configuration

We should either add generators for this (easy but not very extensible) or write a simple maven/gradle-plugin on our own.
