Employees can appear multiple times in the org chart
Purpose
=======
Allow recursive hierarchy (an employee can be its own manager; e.g. the CEO is manager of everyone
but is also member of a department managed by the CTO who is himself managed by the CEO).
This means an employee might appear in multiple place in the organisational chart.
The button to see more of the hierarchy in the organisation chart opens all employees under the N+2 of the
current employee being displayed but does not open the view of the N+2.
Specification
=============
Add 'subordinates_ids' computed field on 'hr.employee' to get all subordinates (direct and indirect).

This commit introduces a new widget specific to employees. It is used
to display an org chart centered on the current displayed employee.
Two levels of managers as well as subordinates are displayed.
It is contained in its own module and its installation is available from
hr settings.
Thanks to Stefano Rigano <sri@odoo.com> (@stefanorigano) for design and UX
implementation.
