Update SugarCacheRedis.php to allow Secured Redis with AUTH

[J-Wick4]

Added Redis Authentication for secured Redis installations, along with database selection.

Description

This change enables authentication with Redis/Valkey for extra security.

Motivation and Context

This solves security with Redis/Valkey in case of multiple users.

How To Test This

After updating to this version of SugarCacheRedis.php update your config_override.php file with the following:

$sugar_config['external_cache']['redis']['host'] = 'localhost';
$sugar_config['external_cache']['redis']['port'] = 6379;
$sugar_config['external_cache']['redis']['password'] = 'PASSWORD';
$sugar_config['external_cache']['redis']['database'] = 1;
$sugar_config['external_cache_disabled_redis'] = false;

Clear your cache and check your Redis/Valkey for populated values.
