Add "Retry all" button to the Failed Jobs page

[odinserj]

As an administrator, I want to retry all my failed jobs at once. To do this I go to the Failed jobs page and click the "Retry all" button in the top toolbar. When the operation completes, I want to know, how many tasks were re-queued, and how many tasks were not re-queued.

All failed jobs should proceed to the Enqueued state only from Failed state, because someone can change job's state during retry task execution.
