### What problem does this PR solve?

If you deploy Ragflow using Kubernetes, the hostname will change during
a rolling update. This causes the consumer name of the task executor to
change, making it impossible to schedule tasks that were previously in a
pending state.
To address this, I introduced a recovery task that scans these pending
messages and re-publishes them, allowing the tasks to continue being
processed.

### What problem does this PR solve?

After being idle for a while (When Redis Queue exceeds the
SVR_QUEUE_RETENTION(60*60) expiration time), new tasks need to be cancel
and redo.

When use xgroup_create to create a consumer group, set the ID to "$",
meaning that only messages added to the stream after the group is
created will be visible to new consumers. If the application scenario
requires processing messages that already exist in the queue, you might
need to change this ID to "0", so that the new consumer group can read
all messages from the beginning.
