(cherry picked from commit 31a03d7ae8075d29519272214989e111ef4e374e)

Motivation:

Avoid callback handlers in the MyVerticle examples, use a Future instead.

@julianladisch note this chapter is being rewritten in Vert.x 5 because we want to offer a new model based on Future instead of promise completion, see https://github.com/eclipse-vertx/vert.x/pull/5318
