[MGR] configuration_helper

* [PORT] [9.0] configuration_helper
Port to API 8.0 and make it compatible with a config definition in API
8.0. Remove some hacks with onchange and write to get and set the
related values.

* Add a module to define classes in order to test configuration_helper

+Configuration Helper
+====================
+
+*This module is intended for developer only. It does nothing used alone.*
+
+It helps to create `config.settings` by providing an abstract Class.
+
+This class:
+
+  * creates automatically related fields in 'whatiwant.config.settings'
+    using those defined in 'res.company': it avoids duplicated field definitions.
+  * company_id field with default value is created
+  * onchange_company_id is defined to update all related fields
+  * supported fields: char, text, integer, float, datetime, date, boolean, m2o
+
+
+How to use
+----------
+
+.. code-block:: python
+
+    from . company import ResCompany
+
+    class WhatiwantClassSettings(orm.TransientModel):
+        _inherit = ['res.config.settings', 'abstract.config.settings']
+        _name = 'whatiwant.config.settings'
+        # fields must be defined in ResCompany class
+        # related fields are automatically generated from previous definitions
+        _companyObject = ResCompany
+        # all prefixed field with _prefix in res.company, will be available in 'whatiwant.config.settings' model
+        _prefix = 'prefixyouchoose_'
+
+
+Roadmap
+-------
+  * support (or check support) for these field types : o2m, m2m, reference, property, selection
+  * automatically generate a default view for 'whatiwant.config.settings' (in --debug ?)
