Boaz Leskes ecf81688fb Use sequence numbers to identify out of order delivery in replicas & recovery (#24060) ...

Internal indexing requests in Elasticsearch may be processed out of order and repeatedly. This is important during recovery and due to concurrency in replicating requests between primary and replicas. As such, a replica/recovering shard needs to be able to identify that an incoming request contains information that is old and thus need not be processed. The current logic is based on external version. This is sadly not sufficient. This PR moves the logic to rely on sequences numbers and primary terms which give the semantics we need.
