GCS DeleteBucket expects the bucket to be empty to be deleted

[shrutimantri]

Expected Behavior

The given bucket should be deleted. We can provide an option to delete non-empty bucket, or explicitly mention that only empty buckets will be deleted.

Actual Behaviour

The non-empty bucket does not get deleted. The task fails with the following error:

[anna-geller]

this seems expected, I know it from S3 that this is the default behavior

initially this seems safer than deleting a non empty bucket

we could introduce an option to force delete in the style of gsutil -m rm -r gs://my-bucket
