When I tried to perform non-read operations (create_bucket, delete_object, put_object...) over IBM COS (and with iam_api_key auth.), I got this error:

During handling of the above exception, another exception occurred:

ibm_botocore.exceptions.ClientError: An error occurred (InvalidArgument) when calling the CreateBucket operation: Invalid Argument

Basically, it was due to IBM COS client miss the ibm_service_instance_id info.

This PR will fix this issue.
