### What changes were proposed in this pull request?
Support min number of workers to assign slots on for a shuffle.
### Why are the changes needed?
PR https://github.com/apache/celeborn/pull/3039 updated the default value of
`celeborn.master.slot.assign.extraSlots` to avoid skew in shuffle stage with
less number of reducers. However, it will also affect the stage with large
number of reducers, thus not ideal.
We are introducing a new config `celeborn.master.slot.assign.minWorkers`
which will ensure that shuffle stages with less number of reducers will not
cause load imbalance on few nodes.
### Does this PR introduce _any_ user-facing change?
Yes
### How was this patch tested?
NA
