erp5 kernel jupyter

ipython_notebook SR hooked with ERP5 kernel. This kernel helps in interaction between erp5 and Jupyter frontend. The patches have been cleaned up Features: - All the code execution is being done at erp5 side, Jupyter just acts as dumb client. - Receives result as string and its mime_type and thanks to kernel, displays it accordingly. - Interactions b/w erp5 and Jupyter frontend are based on HTTP requests. Major changes: - Addition of erp5 kernel - Improvement in code according to guidelines(name, section name) - Use jinja template as instance file and make it more dynamic - Debugging added for ipython_notebook service. Note: The certificate authentication changed has been reverted to the previous one(done by creating wrapper around openssl command) for now. /cc @Tyagov /reviewed-by @kirr, @jerome (on nexedi/slapos!33)

+/**
+ *
+ *
+ * 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) {
+ *         events.on("app_initialized.NotebookApp", function () {
+ *             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(){
+ *            IPython.toolbar.add_buttons_group([
+ *                {
+ *                    'label'   : 'run qtconsole',
+ *                    '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
+ *    $.getScript('/static/notebook/js/celltoolbarpresets/slideshow.js');
