Feature workspace/Draft

[Delawen]

The idea is simple:

When a published metadata is edited, a new copy is saved on both the database and the index marked with the draft flag. This way a user with enough privileges can view, search and edit published metadata without modifying what the rest of the users see about this metadata. This is specially useful for long editings (that last more than one session) or edits that need some kind of review from several users before getting published.

This draft is blocked while a user is editing it to prevent other concurrent editing with other users. This block is released either when the editor is closed or after a timeout of inactivity. Once the draft copy is published, the original published metadata gets replaced with the draft copy and the draft is removed from the system.

Drafts will be saved on a different table on the database, so we can keep a unique identifier by uuid on the metadata table. The lucene index will be the same, just adding the "draft" flag.

So, Travis does not agree with me. Also, it fails on places I haven't modified 🤔

Locally, all tests run fine:

Ok this is a nightmare. I'm giving up on this branch.

Starting from scratch. Wait for my smaller but concatenated PR in the following days...
