Subject: [PATCH] Enable Lazy service for phpredis (#440)

The service will be lazy if symfony/proxy-manager-bridge is installed
As a consequence it will allow to warmup the cache even if Redis server is not reachable

+## Troubleshooting ##
+
+If cache warmup fails for prod because a redis server is not available,
+try to install [`symfony/proxy-manager-bridge`](https://symfony.com/doc/master/service_container/lazy_services.html):
+
+``` bash
+$ composer require symfony/proxy-manager-bridge
+```
+
+Once done some services will be lazy-loaded and could prevent unwanted connection call.
