[ADD][9.0] medical_base_kanban: Module for abstract stages

[lasley]

• Create a model to handle abstract stages with Kanban

Medical Base - Kanban

This module provides abstract KanBan logic for use in Medical Resources.

Usage

The medical.base.kanban model should be inherited in order to add KanBan
and Stage functionality to any record

class MyModel(models.Model):
    _name = 'my.model'
    _inherit = 'medical.base.kanban'

A Base KanBan view is also provided, which can be integrated into child views

<record id="my_model_kanban_view" model="ir.ui.view">
    <field name="name">My Record</field>
    <field name="model">my.model</field>
    <field name="inherit_id" ref="medical_base_state.medical_base_kanban_view" />
    <field name="arch" type="xml">
        <!-- Add your contextual changes here w/ XPath -->
    </field>
</record>

We have abstracted this logic and moved to the web repo. As such, this PR is superseded by OCA/web#490.
