ReadMany: Adds ReadManyItems Api using Query under the covers

[asketagarwal]

Sample

Stream:

  IReadOnlyList<(string, PartitionKey)> itemList = new List<(string, PartitionKey)>
  {
       ("Id1", new PartitionKey("pkValue1")),
       ("Id2", new PartitionKey("pkValue2")),
       ("Id3", new PartitionKey("pkValue3"))
  };
   
   using (ResponseMessage responseMessage = await this.Container.ReadManyItemsStreamAsync(itemList))
   {
       using (Stream stream = response.ReadBodyAsync())
       {
           //Read or do other operations with the stream
           using (StreamReader streamReader = new StreamReader(stream))
           {
               string content = streamReader.ReadToEndAsync();
           }
       }
   }

Typed:

   public class ToDoActivity{
       public string id {get; set;}
       public string status {get; set;}
   }
  
   IReadOnlyList<(string, PartitionKey)> itemList = new List<(string, PartitionKey)>
   {
       ("Id1", new PartitionKey("pkValue1")),
       ("Id2", new PartitionKey("pkValue2")),
       ("Id3", new PartitionKey("pkValue3"))
   };
  
  FeedResponse<ToDoActivity> feedResponse = this.Container.ReadManyItemsAsync<ToDoActivity>(itemList);

This is crafty, good one

LGTM, the only points are around the semaphore wait that Kiran already pointed out

Do PKRangeId show up in the trace-data?

[j82w]

Yes, query adds the PKRangeIds
