Bad status code from gs display an error from s3 driver

[maingoh]

When using GoogleStorageDriver and getting a 502 we get a confusing error: <LibcloudError in <class 'libcloud.storage.drivers.s3.S3StorageDriver'> 'Unknown error. Status code: 502'>

Probably due to the fact that GoogleStorageDriver inherit from BaseS3StorageDriver https://github.com/apache/libcloud/blob/881d5fb0b8973a0f1037e0aa0d3538b407f57d26/libcloud/storage/drivers/s3.py#L141
