software/jupyter: move to python 3

moves python2 release to component/jupyter-py2 because it is required by ERP5
but not maintained anymore

moves to python 3 :
- test/test.py
- jupyter_notebook_config.py.jinja
- ERP5kernel.py

modifies custom.js to create a workaround for events issue
see (https://github.com/jupyter/notebook/issues/2499)

upgrades slapos.cookbook version to 1.0.171 to use zero_knowledge recipe
with python 3

adds jupyter partition check in software/erp5/test/test_erp5.py

component/jupyter-py2/README.md

+This directory is only temporary (until ERP5 is Python3) and will not actively
+be maintained.
+
+It has to be removed once ERP5 uses `software/jupyter` or do not use jupyter at
+all.

+ *
+ *
+ * Placeholder for custom user javascript
+ * mainly to be overridden in profile/static/custom/custom.js
+ * This will always be an empty file in IPython
+ *
+ * User could add any javascript in the `profile/static/custom/custom.js` file.
+ * It will be executed by the ipython notebook at load time.
+ *
+ * Same thing with `profile/static/custom/custom.css` to inject custom css into the notebook.
+ *
+ *
+ * The object available at load time depend on the version of IPython in use.
+ * there is no guaranties of API stability.
+ *
+ * The example below explain the principle, and might not be valid.
+ *
+ * Instances are created after the loading of this file and might need to be accessed using events:
+ *     define([
+ *        'base/js/namespace',
+ *        'base/js/events'
+ *     ], function(IPython, events) {

+ *             IPython.keyboard_manager....
+ *         });
+ *     });
+ *
+ * __Example 1:__
+ *
+ * Create a custom button in toolbar that execute `%qtconsole` in kernel
+ * and hence open a qtconsole attached to the same kernel as the current notebook
+ *
+ *    define([
+ *        'base/js/namespace',
+ *        'base/js/events'
+ *    ], function(IPython, events) {
+ *        events.on('app_initialized.NotebookApp', function(){

+ *                    'icon'    : 'icon-terminal', // select your icon from http://fortawesome.github.io/Font-Awesome/icons
+ *                    'callback': function () {
+ *                        IPython.notebook.kernel.execute('%qtconsole')
+ *                    }
+ *                }
+ *                // add more button here if needed.
+ *                ]);
+ *        });
+ *    });
+ *
+ * __Example 2:__
+ *
+ * At the completion of the dashboard loading, load an unofficial javascript extension
+ * that is installed in profile/static/custom/
+ *
+ *    define([
+ *        'base/js/events'
+ *    ], function(events) {
+ *        events.on('app_initialized.DashboardApp', function(){
+ *            require(['custom/unofficial_extension.js'])
+ *        });
+ *    });
+ *
+ * __Example 3:__
+ *
+ *  Use `jQuery.getScript(url [, success(script, textStatus, jqXHR)] );`
+ *  to load custom script into the notebook.
+ *
+ *    // to load the metadata ui extension example.
+ *    $.getScript('/static/notebook/js/celltoolbarpresets/example.js');
+ *    // or
+ *    // to load the metadata ui extension to control slideshow mode / reveal js for nbconvert

+  1. Make sure you have 'erp5_data_notebook' business template installed in your ERP5</br>\
+  2. <b>%erp5_user &lt;your_erp5_username&gt;</b></br>\
+  3. <b>%erp5_password &lt;your_erp5_password&gt;</b></br>\
+  4. <b>%notebook_set_reference &lt;your_notebook_reference&gt;</b></br>\
+  It would be better to set the reference to match with erp5 reference pattern.</br>\
+  5. As soon as you see 'Please Proceed' message you can now access your erp5 using notebook.</br>\
+  <p><u>OTHER USEFUL MAGICS</u> -</br>\
+  <b>%my_notebooks</b> -This is used to display all the notebooks created by the specific user.</br>\
+  <b>%notebook_set_title</b> -This sets the title of the current notebook.</br>\
+  NOTE: Do not dynamically alter imported module objects as they are not being saved in DB, </br>\
+  so changes to them would be disregarded and would throw an error.</br>\
+  <p><u>About classes, functions and global state on modules:</u></p>\
+  Your code is going to be executed by ERP5, which can have many nodes </br>\
+  and there is no guarantee that your code is always going to be executed by the same server.</br>\
+  This means that objects which cannot be stored in the ZODB, like functions, classes and modules </br>\
+  won't be available across nodes. To solve this issue, you need to use a special object </br>\
+  called 'environment' to store your global setup. This object was designed to hold global </br>\
+  state and restore it for each code cell. Example:</br></br>\
+  <b>def my_setup():</br>\
+     # import modules, define functions and classes</br>\
+     # and set global state on modules</br>\
+     # return dict of variables to be available in code cells</br>\
+     {'my_var': 1}</br>\
+  environment.define(my_setup, 'my custom setup')</b></br></br>\
+  After you execute this cell, the <b>my_setup</b> function will run before each of the</br>\
+  following cells and the <b>my_var</b> variable will be created and set to 1.</br></br>\
+  <b>WARNING:</b> it is not recommended to have too many setup functions in the environment, </br>\
+  because they will be executed in every code cell and can cause a substantial slow down.\
