Currently health checks depends on Vert.x Web and Vert.x Auth. We would like to remove this dependency in Vert.x 5 by moving this part to Vert.x Web and have only health checks to define the API/SPI.

• implement the health check handler in Vert.x Web
  Implement the health check handler in Vert.x Web vertx-web#2432
• update Hazelcast CM
  Nothing to do, still depends on vertx-web (for docs and tests)
• update Infinispan CM
  Nothing to do, still depends on vertx-web (for docs and tests)
• remove the handler in Vert.x Health Check and other dependencies (e.g. jdbc-client for testing)
  Remove HealthCheck handler for Vert.x Web eclipse-vertx/vertx-health-check#57
• document breaking change
