AVX-51277: Do not set bucket_name for config backup in Azure.

On the controller we have a bound validator that ensures that the `bucket_name`
parameter is non-empty.  When we send a request to backup configuration for
Azure, we use a set of different parameters and we do not set `bucket_name`.
This causes validation to fail for Azure.
