Swift backend can not register item with href containing a bucket name
In a situation that we do not know beforehand from which bucket we are registering in swift and want to encode the bucket into the path, currently the bucket name is prepended twice in VSI calls during registration. This issue is already solved for S3, so the task is to review the s3 code path and adjust swift code path accordingly.
Not urgent to solve, as we are not registering from source object storage directly yet.
