Several responses include the shards_acknowledged flag ( indicating whether the requisite number of shard copies started before the completion of the operation ) and there are two different getters used : isShardsAcknowledged() and isShardsAcked()

public boolean isShardsAcknowledged()

• OpenIndexClusterStateUpdateResponse
• OpenIndexResponse

public boolean isShardsAcked()

• CreateIndexClusterStateUpdateResponse
• RolloverResponse
• CreateIndexResponse

Should they be unified?
