Allow kernel configuration via data provider

[jdreesen]

This follows #8 and #11 and adds support for configuring the kernel via data providers:

use Neusta\Pimcore\TestingFramework\Test\Attribute\ConfigureExtension;
use Neusta\Pimcore\TestingFramework\Test\ConfigurableKernelTestCase;

class SomeTest extends ConfigurableKernelTestCase 
{
    public function provideTestData(): iterable
    {
        yield [
            'some value', 
            new ConfigureExtension('some_extension', ['config' => 'some value']),
        ];

        yield [
            new ConfigureExtension('some_extension', ['config' => 'other value']), 
            'other value',
        ];
    }

    /** @dataProvider provideTestData */
    public function test_something(string $expected): void
    {
        self::assertSame($expected, self::getContainer()->getParameter('config'));
    }
}

All kernel configuration objects (RegisterBundle, ConfigureContainer, ConfigureExtension, and RegisterCompilerPass) can be used and are removed from the arguments passed to the test method, so their position doesn't matter.
