[RFE] Surface the Task Manager in the UI

[rromannissen]

What is the problem?

There's no way for the user to understand which tasks are being executed and the queue of pending tasks.

Why is this a problem?

By not knowing what is being executed and scheduled at a given moment, users might feel like the system is unresponsive, especially in multi-user environments.

Proposed solution

Surface information about what is queued for execution by the task manager. This view should provide a way for users to:

• Browse the task queue. For each task the following information should be provided:
  • Task ID.
  • Task type: Analysis, discovery...
  • User that created the task.
  • Status: Scheduled, In progress...
• Cancel background tasks like automatic language/technology stack discovery (see [RFE] Automatic language and technology discovery for applications #170 for more information about this). Cancelled background tasks will be rescheduled again automatically at the end of the queue.
• Cancel the tasks created by the current user. Tasks created by other users can't be cancelled.
