Feature: #107725 - Support username for authentication in Redis cache backend 

See forge#107725

Description 

Since Redis 6.0, it is possible to authenticate against Redis using both a username and a password. Prior to this version, authentication was only possible with a password. With this change, the Redis cache backend in TYPO3 now supports both authentication mechanisms.

You can configure the Redis cache backend as follows:

config/system/additional.php 
use TYPO3\CMS\Core\Cache\Backend\RedisBackend;

$GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['pages']['backend'] = RedisBackend::class;
$GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['pages']['options']
    = [
        'defaultLifetime' => 86400,
        'database' => 0,
        'hostname' => 'redis',
        'port' => 6379,
        'username' => 'redis',
        'password' => 'redis',
    ];
Copied!

Impact 

The RedisBackend now supports authentication using both a username and a password.

The password configuration option is now typed as array|string. Using an array for this configuration option is deprecated and will be removed in TYPO3 v15.0.
