Karel Hala One thing I just noticed from the Cost Mgmt logs.

`{'billing_source': {'data_source':

{'provider.data_source': [ErrorDetail(string="One or more required fields is invalid/missing. Required fields are ['bucket']", code='invalid')]}

}}`

I believe this is because the wizard is sending `bucket_name` instead of `bucket` in the extras field. So we need to make a minor tweak to fix that.
