[ADD] pad: new etherpad plugin to remove autofocus

In the form views where the pads are used, Etherpad-lite automatically
focus on the pad content, even if the user has already started to type
into another field.

This behavior is quite annoying for "quick changes", so we provide a
(very tiny) plugin for Etherpad-lite that will prevent this autofocus.

Detailed installation instructions are also included.

+Readme
+======
+
+`ep_disable_init_focus` is a very simple
+[Etherpad-lite](https://github.com/ether/etherpad-lite) plugin, which disable
+the focus on the pad content after its loading.
+
+Rationale
+---------
+
+Etherpad-lite autofocus can be annoying to end-users when it is used in Odoo's
+"pad" widget, because it will override web client focus rules. This plugin is
+design to get rid of this behavior.
+
+
+Installation instructions
+-------------------------
+
+1. Stop your Etherpad-lite server.
+2. Copy the `ep_disabl_init_focus` folder into the `node_modules` folder of
+   your Etherpad-lite installation.
+3. in the folder of your Etherpad-lite installation, run this command to
+   install the plugin:
+
+    ```sh
+    npm install node_modules/ep_disable_init_focus/
+    ```
+4. Restart the Etherpad-lite server.
