示例1: CreateArtifact
// CreateArtifact creates a new artifact in a open bucket.
//
// If an artifact with the same name already exists in the same bucket, we attempt to rename the
// artifact by adding a suffix.
// If the request specifies a chunked artifact, the size field is ignored and always set to zero.
// If the request is for a streamed artifact, size is mandatory.
// A relative path field may be specified to preserve the original file name and path. If no path is
// specified, the original artifact name is used by default.
