feat: allow to replace queues completely

[katsanva]

This target to sync 1:1 queues that are available in-app and in bull-board.

The pseudocode here is

const queues = [];

setQueues(queues);

app.use("/", UI);

app.post("/queues", (req, res) => {
  queues.push(new Queue(...req.body));

  setQueues(queues); // this one is ok, we're adding a queue
});

app.delete("/queues/:id", () => {
  queues.splice(req.params.id, 1);

  // setQueues(queues); // this one will not work, because it doesn't perform a removal
  replaceQueues(queues);
});
