How to use the azure._str_or_none function in azure

x_ms_lease_id: Required if the blob has an active lease.
        progress_callback:
            Callback for progress with signature function(current, total) where
            current is the number of bytes transfered so far, and total is the
            size of the blob, or None if the total size is unknown.
