[Fiware-developer-experience] Docker base images

[Alvaro del Castillo]

Hi all!

Right now we are using as base images for CentOS and Ubuntu the Bitergia
ones:

https://registry.hub.docker.com/u/bitergia/fiware-orion/dockerfile/

The idea is to change:

FROM bitergia/centos-6:latest

to the official one.

We have started with our own images to control totally what is included
in the images, but official images are also traceable. So our bet is to
change to official images once we have all images ready in Docker Hub. 

Probably now changes will be needed for the user of devguide images.

Cheers
