[backend] Add feed queue control. Only add jobs if current queue is empty

[backend] Add feed queue control. Only add jobs if current queue is empty

• move from dynamic to static to prevent overlap
• Schedule every 30 sec
• If queue is not empty, put the connector in queue control mode, no work, keep the state
• If queue empty, create the work

Job will not be cumulated but as the scheduling is faster, it should have a better behavior overall
