Redis config cannot accept null values as the given example

[GeoSot]

Proposed changes

According to this example, password and database options can be nullable.

$InstanceCache = CacheManager::getInstance('redis', new Config([
  'host' => '127.0.0.1', //Default value
  'port' => 6379, //Default value
  'password' => null, //Default value
  'database' => null, //Default value
]));

For a given server setup I need these values to be null but, the Config setters didn't accept null values and thrown exception.

@Geolim4 can you update the version, on packagist?

[Geolim4]

Hello,

Sadly I already updated the version last week (8.0.3) so you have to be patient until next month or use dev-master until the next release 👍🏼

Cheers,
Georges.
