Vertex example project running on Apache Karaf

This is a simple sample showing how to run Vertx applications on Apache Karaf.

This includes:

• Vertx and Bus as service
• A customized shell to show:
  • The registered verticles
  • What communications is beeing held on the bus
  • Send data to the bus
  • Put/Get/Remove data from the local map
  • List the Http Server registered
  • Show metrics
• A WhiteBoard Extender to register verticles as services
• A Karaf Feature File
• A Karaf custom Distribution for easy testing
• A submodule as example on how to use this, for "microservices" with vertx
  • Extra Samples
  • Extra feature file to completly install those samples
