[RFC] web_kanban_swimlane

[mathben]

Explication
The kanban support only 1 groupby, to create columns. Many other platform support kanban swimlane, very useful to analyse data with horizontal and vertical line.

Additional context
This web view need to support 2 groupby. Maybe create a new Controller, like KanbanController. It's can be more easy for maintenance.

Maybe do like web_timeline, or view graph, adding selection into header to change the groupby for swimlane.

web_timeline :

graph header :

The view activity is a table, without kanban :

Using something like for swimlane and not only filter for kanban :

This module create header and not horizontal line

I need the swimlane to create module project_scrummer OCA/project-agile#47

Into Odoo 11, Modoolar create scrummer with support swimlane, but it was external view integrate into Odoo, the maintenance was complicate and migration with owl block the project.
