[ADD] hr_fleet: Add claim report and cars history per employee

Purpose
=======

When an employee leaves the company, the fleet manager must ask to the insurance company
a claim report for this employee. But in oddo, there is no easy way to have an history
of the drivers.

Specification
=============

1/ On the employee form, add a stat button: "x cars". The button shouldn't be displayed if the count = 0.
   Make a bridge (auto_install: True in the manifest) depending on hr (hr.employee) and fleet (fleet.vehicle.assignation.log)
   - Add a field employee_cars_count (computed) to count the amount of cars the employee drove.
   - Add an method action_open_employee_cars, that return an action (ir.actions.act_window)
     that open on the fleet.vehicle kanban filtered on cars the employee had driven.
2/ In this bridge module, add on the fleet.vehicle.assignation.logs a button (like in expense) to upload
   documents about the car for a particular employee (PV, rapport d'assurance, blabla). On the employee
   form view, add an action button (with groups fleet_manager) to print all the related documents
   (all the attachements on the fleet.vehicle.assignation.logs for the employee).
