[PR] Decouple Committer from Kafka and Enable Custom Coordinator Election [iceberg]
kumarpritam863 opened a new pull request, #12460:
URL: https://github.com/apache/iceberg/pull/12460
**Summary**
This **PR** refactors the Committer implementation to remove its tight coupling with Kafka and provide users the flexibility to define their own coordinator election mechanism by implementing the Committer Interface. Currently, the coordinator is elected based on the lexicographically smallest source topic partition, which limits adaptability in different environments.
**Changes Introduced**
1. Config is exposed which can be used to provide the implementation class.
2. Dynamically loads the user's committer implementation with proper constructor parameters and extra configs in case needed for other settings.

@bryanck Since we are making the committer configurable , so I think this is the right time we should remove the deprecated methods of the committer and via configure give the full control to the user for deciding how they want to write their committer and to be in line I made that change in the default CommitterImpl. Let me know your thoughts.
