The MR is empty because i'm unsure where to put the code. (For now I use the custom plugin mechanism). Let discuss it first.
This MR create a page that can be used to manage sessions (delete) and see oidc token (Maybe I should add the possibility to delete a single oidc token instead of the whole associated session)
This feature could be added as a plugin. (But there is no link to the page except if added as an portal app. Or as a portal module. Don't what would be the bests.
