XD-DENG commented on issue #3823: [AIRFLOW-2985] An operator for S3 object copying

   Hi @feng-tao , my day-to-day use cases are normally copying within one bucket. But I believe copying across buckets is allowed. I'm trying to refer to `boto3` documentation
   1. https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/s3.html#S3.Client.copy_object
   2. https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/s3.html#S3.Client.copy.
   
   One sample provided in the documentation is 
   ```
   import boto3
   s3 = boto3.resource('s3')
   copy_source = {
       'Bucket': 'mybucket',
       'Key': 'mykey'
   }
   s3.meta.client.copy(copy_source, 'otherbucket', 'otherkey')
   ```
   which is an across-buckets case.
