Session refresh on user rights change

[SYNchroACK]

Use case

1. john with permission to view/create/update knowledge will be able to edit an observable.
2. The admin removes all permissions from john but john will still be logged in.
3. john within his session, will edit another observable successfully
4. john logouts and then login again and it will not be able to do anything, even if try to access directly the observable.

Current Workaround

I performed the same test and before the step 4, I deleted the session (http://localhost:8080/dashboard/settings/accesses/sessions) from user john and john automatically lost his access.

Proposed Solution
