Title: Show the timestamp when tasks are picked up by workers

Unlike task.start_time, this one is to show when the task actually starts running. This is helpful when I sometimes notice a task scheduled for a long time in the dashboard and wonder how long it actually runs.

Also I chimed in worker_running attributes in the api return. It is nice to have sometimes when trying to debug hanging tasks.
