Notable breaking changes

• ChattyResponsePredicate removed. Use ChattyHttpResponseExpectation instead. Example:
  Old:

  client .get(8080, "example.com", "/some-uri") .expect(ChattyResponsePredicate.SC_SUCCESS) .send()

  New:

  client .get(8080, "example.com", "/some-uri") .send() // new order! .expecting(ChattyHttpResponseExpectation.SC_SUCCESS)

• GenericCompositeFuture removed. The same methods exists in Vert.x' Future now.

• Futurization of Verticle:

  • AbstractVerticle becomes VerticleBase

  • public void start(Promise<Void> promise) becomes public Future<?> start()

  • public void stop(Promise<Void> promise) becomes public Future<?> stop()
