Let's `Config` static properties to non-static.

[Moln]

I will try use it combine swoole for connect multiple replications. Let's Config static properties to non-static will be better.

$config = (new ConfigBuilder())
    ->withUser('root')
    ->withHost('192.168.1.10')
    ->withPort(3306)
    ->withPassword('123456')
    ->build();

$config2 = (new ConfigBuilder())
    ->withUser('root')
    ->withHost('192.168.1.11')
    ->withPort(3306)
    ->withPassword('123456')
    ->build();

var_dump($config->getHost()); //192.168.1.11

Expected Result.

Output: 192.168.1.10

Actual Result.

Output: 192.168.1.11
