Allow the definition of custom collections

[sebdeleze]

In Dedicated portals, organisations have the possibility to create custom collections. Each collection:

• has its own URL (ex. https://mysonarportal.org/collection/ABC)
• has an entry page with a description and an image, and it shows by default all the related publications
• appears in the "Collection" facet
• gathers publications based on the contents of the specificCollections metadata field
• (to be discussed: has a short code)

To manage these collections, I think we have to create a new resource collections. With such a resource, we can specify an identifier, a title, a description and an image.
And the specificCollections will be transformed to point to one or more collections reference.
Unfortunately, we will have to do a mass correction in production and a complete re-indexing.
Is this behavior OK for you?
