RATIONALE Currently when an ir.model.fields is removed all tracking linked to it is lost. Indeed field is required and has an ondelete cascade attribute set to it. However we should keep tracking values as those made sense when used and one could want to have access to this information. SPECIFICATIONS When removing fields set the field to False instead. Add a new field to store fields information allowing to keep name, type and groups information to allow displaying removed tracking values. Use this field only when a field is removed to avoid duplicating field information when not necessary and polluting the table.
