Apply CreateSeekableStreamAsync all around the site

[infofromca]

Make

private static async Task<Stream> CreateSeekableStreamAsync(Stream stream, CancellationToken cancellationToken)
 {
     var tempFilePath = Path.Combine(Path.GetTempPath(), Path.GetRandomFileName());
     var tempStream = new FileStream(
         tempFilePath,
         FileMode.CreateNew,
         FileAccess.ReadWrite,
         FileShare.None,
         81920,
         FileOptions.Asynchronous | FileOptions.DeleteOnClose);

     try
     {
         await stream.CopyToAsync(tempStream, cancellationToken);
         tempStream.Position = 0;

         return tempStream;
     }
     catch
     {
         await tempStream.DisposeAsync();
         throw;
     }
 }

public and apply it to all the site,
1--one place for the logic
2--consistent

What's the issue? Or the suggestion that you want to discuss?

I don't think we should do this everywhere as it's bad for performance. AFAIK this is a specific case for the new ClamAV service, it should stay there.
