This story deal with minimal folder display:

• A table showing the folder's contents is displayed.
• For each item:  Item name | owner | last update date is displayed
• owner has its avatar and its name is clickable
• documents have their icon and color displayed (like mockup)
  • /!\ documents are not clickable, will be done in a dedicated story
• folders are clickable (=> vue routing)
  • on click on folder name, user is redirected into the folder
  • there is a spinner during the load of folder (see mockup + see https://cdn.dribbble.com/users/405422/screenshots/2439719/dribbble.gif for the css loading animation)
  • if there is an error
    • A message is displayed and a link enable user to go back on the parent folder
  • once we are "redirected" into the folder, the breacdrumb is updated
    • if user clicks on UI, the breadcrumb is completed by javascript
    • if user comes from a direct link, then we do recursive GET to fetch parent until we are able to display the breadcrumb globally
• we do not keep the old behaviour of item ranking, it follows the standard pattern:
  • Folders, then files in lexicographic order

We need a new REST route to get the contents of a folder, the route returns all folders and documents contained in a folder:

/!\ REST route must deal with permissions
