Add the possibility to have the kanban WIP limit in columns

Hello,
What do you mean by the WIP limit?

The Work In Progres Limit (WIP) of kanban method defines the maximun number of tickets/tasks you can be working on at the same time. You can read more information here: https://kissflow.com/project/agile/wip-limits-in-kanban/

This doesn't seem related at all to Kanban, but instead would be a global restriction. The Kanban is just a different way to view tickets/projects/etc. We would have to add global options for restricting the number of project tasks that can be in a specific status at the time and then that would affect the regular form UI, gantt view and the Kanban.
