MAGETWO-84608: Cannot perform setup:install if Redis needs a password…

[guillaumegiordana]

Description

Needed to perform setup on a fresh magento install using an authenticated redis instance for the cache configuration part.
Redis session password configuration works whereas the cache configuration does not take the provided configuration.
Changed setup/src/Magento/Setup/Model/ConfigOptionsList/Cache.php and setup/src/Magento/Setup/Model/ConfigOptionsList/PageCache.php to enable a configuration password during initial setup.

Fixed Issues (if relevant)

1. magento/magento2#MAGETWO-84608: Redis password not used when trying to validate the connection during install.

Manual testing scenarios

1. Setup a new magento instance with bin/magento setup:install with cache options in env.php as so :
   'cache' => [ 'frontend' => [ 'default' => [ 'backend' => 'Cm_Cache_Backend_Redis', 'backend_options' => [ 'server' => redis_host, 'database' => '0', 'port' => 6379, 'password' => redis_password ] ], 'page_cache' => [ 'backend' => 'Cm_Cache_Backend_Redis', 'backend_options' => [ 'server' => redis_host, 'port' => 6379, 'database' => '1', 'compress_data' => '0', 'password' => redis_password ] ] ] ],

The setup will fail saying that the redis configuration is wrong.
