Add "About" topics to EGI service catalogues

From @brucellino on Thu Apr 05 2018 14:42:30 GMT+0000 (UTC)

The EGI services have existing descriptions, helpdesks, and communication channels. They can still be discussed, but we should make these clear in their respective “About” topics that get pinned to the top of each subcategory.

We can just take the description from the web page and add it to a template in files/, then add a few extra service-specific links.

The workflow should be something like :

  1. Get the topic
  2. Update the first post of the topic with the template string.

A script to do this should be provided.
