[server] Make connection pooler configurable and set better default values
Drop the configuration connections-pool-size and add new configurations options:
* connections-pool-min-size. Set to 0 by default so we open connections only
when needed. This avoid opening min-size*processes connections at startup,
which is, it think, a good default.
* connections-pool-max-size. Set to 0 (unlimited) by default, so we move the
bottleneck to postgresql.
* connections-idle-timeout. Set to 10 minutes. I don't have arguments about
this except that this is the default in pgbouncer.

Building a simple blog with |cubicweb|
======================================
|cubicweb| is a semantic web application framework that favors reuse and
object-oriented design.
This tutorial is designed to help in your very first steps to start with
|cubicweb|. We will tour through basic concepts such as:
* getting an application running by using existing components
* discovering the default user interface
* basic extending and customizing the look and feel of that application
More advanced concepts are covered in :ref:`TutosPhotoWebSite`.
.. _TutosBaseVocab:
Some vocabulary
---------------
|cubicweb| comes with a few words of vocabulary that you should know to
understand what we're talking about. To follow this tutorial, you should at least
know that:
* a `cube` is a component that usually includes a model defining some data types
and a set of views to display them. A cube can be built by assembling other
cubes;
* an `instance` is a specific installation of one or more cubes and includes
configuration files, a web server and a database.
Reading :ref:`Concepts` for more vocabulary will be required at some point.
Now, let's start the hot stuff!
