Jira Link: DB-3156 See: https://github.com/yugabyte/yugabyte-db/blob/dc811063af47a1727cbe59e5ce621f2e94da71c9/src/yb/docdb/wait_queue.cc#L352 https://github.com/yugabyte/yugabyte-db/blob/dc811063af47a1727cbe59e5ce621f2e94da71c9/src/yb/docdb/conflict_resolution.cc#L656

Instead of re-running conflict resolution in these cases, just rollback the transaction and fail the operation

This should not impact fairness. Consider closing this as it might not add as much value.
