### What changes were proposed in this pull request?
Enhancing the logic of https://github.com/apache/celeborn/pull/3496
### Why are the changes needed?
https://github.com/apache/celeborn/pull/3496 only handles the reduce side
flow i.e GetReducerFileGroup request will fail if the shuffle data is mark
lost.
In this PR, we are making use of the `WorkerStatusListener` to immediately
detect the lost workers, mark the data lost of the stage and immediately issue
stage end for that stage. This will also allow write stage to fast-fail during
revives and commit request, otherwise write stage will run as usual and then
reduce will fail at startup. This will lead to lot of resource and time wastage.
