Evaluation of loops in templated variables
currently b2shareOperator returns only one file that will be copied with SFTPOperator (compare to taskflow where a list of files is used).
Solution, similarly to taskflow we could use hook and iterate thorugh the list.
Alternative: is it possible to still use SFTPOperator and work with list? Loop in a template or something? This task is more about learning how to solve problems in an non intrusive manner with airflow.
