OpenSearch: [BUG] Breaking changes for CCR plugin in OS 2.0

Describe the bug CCR depends on IndexShard(getHistoryOperations) to retrieve translog operations for leader index. In 2.0, this method is removed in this PR: https://github.com/opensearch-project/OpenSearch/pull/2077

 public Translog.Snapshot getHistoryOperations(String reason, Engine.HistorySource source, long startingSeqNo, long endSeqNo)

Expected behavior

Please provide replacement for this method in 2.0 to retrieve operations based on history-source.
