Allow socket connection to MySQL

[Neraste]

Issue details

When I try to install the app with the pdo_mysql driver communicating by Unix socket, I get the following error when doing php bin/console wallabag:install --env=prod:

Step 2 of 5. Setting up database.

Steps to reproduce/test case

Just tried to install it following the install guide, except that there are no directives for a Mysql install.

Used the following app/config/parameters.yml file:

# This file is auto-generated during the composer install
parameters:
    database_driver: pdo_mysql
    database_host: socket:/var/run/mysql/mysql.sock # also tried socket:///var/run/mysql/mysql.sock
    database_port: null
    database_name: symfony
    database_user: symfony_user
    database_password: __password__
    database_path: '%kernel.root_dir%/../data/db/wallabag.sqlite'
    database_table_prefix: wallabag_
    mailer_transport: smtp
    mailer_host: 127.0.0.1
    mailer_user: null
    mailer_password: null
    locale: fr
    secret: ovmpmAWXRCabNlMgzlzFXDYmCFfzGv
    twofactor_auth: true
    twofactor_sender: __address__
    fosuser_confirmation: true

Thanks for reporting this to us, we did not provide configuration for connection using sock right now.
The fix is easy to produce.*

We need to add the option unix_socket in the config.yml file (see).
