Create configuration file to select experiments to display.

[psaiz]

The template for the portal displays experiment specific configuration in there places

• Icon of the experiment at the bottom of the page
• Drop down menu on About
• Link under Focus
  The thing is that some of those experiments should be displayed in opendata-qa and not on opendata.cern. At the moment, this is solved by having different images. For instance, there is a v0.2.1, and a v0.2.1-jade (that includes the jade configuration).

It would be better if the image contained all the experiments, and then there was a configuration mechanism to specify which experiments should not be displayed. That way, the same image of the portal can be installed on prod and qa.
