In the assignation logs in hr_fleet, it is possible to access the list of
attachments and upload new files to a certain log. However, we currently
enter the form view for ir.attachment to create the record and many technical
fields are shown that are not necessary. This commit overwrites the kanban view
adding an upload button that will open the file upload dialog of the OS and
automatically add the uploaded files to that certain assignation log.
