List Tasks
'GET /config/server/tasks/'

End-users may see a task only if they can also see the project the task is associated with. Tasks operating on other projects, or that do not have a specific project, are hidden.
Members of a group that is granted the View Queue capability or the Administrate Server capability can see all tasks.
As result a list of TaskInfo entities is returned.
