Resolve "Bulk update due date of issues"

What does this MR do?

Add Bulk update due date of issues

Are there points in the code the reviewer needs to double check?

1. I did not use gl_dropdown since Pikaday stop click event propagate to parent. So I think it is less meaning to use gl_dropdown
2. There is a situation that user may clear the due date. So I set the text as No due date
3. Function is ready but I will add tests later maybe in the next week

Why was this MR needed?

convenient for user to update a bundle of issues for due date
