Split cache from Connection::class:

• Add SchemaCache::class and QueryCache::class.
• Clean more code.
• Update tests.
• Implement Psr\SimpleCache\CacheInterface.

The configuration for the cache is very simple example:

return [
    Aliases::class => [
        '@root' => dirname(__DIR__, 1),
        '@data' =>  '@root/tests/Data',
        '@runtime' => '@data/runtime',
    ],

    CacheInterface::class => [
        '__class' => Cache::class,
        '__construct()' => [
            Reference::to(ArrayCache::class)
        ]
    ],

    SimpleCacheInterface::class => CacheInterface::class,

    LoggerInterface::class => Logger::class,

    ConnectionInterface::class  => [
        '__class' => Connection::class,
        '__construct()' => [
            'dsn' => $params['yiisoft/db-pgsql']['dsn']
        ],
        'setUsername()' => [$params['yiisoft/db-pgsql']['username']],
        'setPassword()' => [$params['yiisoft/db-pgsql']['password']]
    ]
];

Everything is solved by di-container autowired.
