rusoto: s3sink: Implement support for GstUriHandler interface
With the URI handler interface implemented, we can drop the old method of specifying bucket, key and region. This also brings it in line with how it is for s3src.

## s3sink
|
||||
|
||||
Writes data to a specified S3 bucket. The `region` parameter is optional, and
|
||||
if not specified, the default parameter will be used (from `.aws/config` file).
|
||||
Writes data to a specified S3 (region, bucket, object, version?) tuple. The
|
||||
version may be omitted.
