[doc] rearranges Settings & Engines docs for better readability

We have built up detailed documentation of the *settings* and the *engines* over
the past few years.  However, this documentation was still spread over various
chapters and was difficult to navigate in its entirety.

This patch rearranges the Settings & Engines documentation for better
readability.

To review new ordered docs::

+MeiliSearch_ is aimed at individuals and small companies.  It is designed for
+small-scale (less than 10 million documents) data collections.  E.g. it is great
+for storing web pages you have visited and searching in the contents later.
+
+The engine supports faceted search, so you can search in a subset of documents
+of the collection.  Furthermore, you can search in MeiliSearch_ instances that
+require authentication by setting ``auth_token``.
+
+Example
+=======
+
+Here is a simple example to query a Meilisearch instance:
+
+.. code:: yaml
+
+  - name: meilisearch
+    engine: meilisearch
+    shortcut: mes
+    base_url: http://localhost:7700
+    index: my-index
+    enable_http: true
