Implement a Blue-Green Deployment for CloudFoundry

[DEKHTIARJonathan]

I tried many times to implement a Blue-Green deployment for the deployment of the Cloudfoundry applications on Bluemix directly after a Travis, however I never managed to make it work.

It would be very nice to have some help on this.

For now, whenever I push a new commit, the application is firstly completely shut down then updated. Which leave the application offline for like ... 15min ...

There must be other ways to do this without shutdown the service
