Thales Macedo Garitezi fd360ac6c0 feat(buffer_worker): refactor buffer/resource workers to always use queue
This makes the buffer/resource workers always use `replayq` for
queuing, along with collecting multiple requests in a single call.
This is done to avoid long message queues for the buffer workers and
rely on `replayq`'s capabilities of offloading to disk and detecting
overflow.

Also, this deprecates the `enable_batch` and `enable_queue` resource
creation options, as: i) queuing is now always enables; ii) batch_size
> 1 <=> batch_enabled.  The corresponding metric
`dropped.queue_not_enabled` is dropped, along with `batching`.  The
batching is too ephemeral, especially considering a default batch time
of 20 ms, and is not shown in the dashboard, so it was removed.

Fix some issues that could lead to wrong bridge metrics. Fix and issue that could lead to message loss and wrong metrics with Kafka Producer bridge when Kafka or the connection to it is down. Fix some issues that could lead to the same message being delivered more than once when using batching for bridges and when the batch was retried.
