Added the ability to configure additional paths for suite

Added the ability to configure additional paths for suite.

This allows you to focus tests closer to your code.

Example tests/codeception/unit.suite.dist.yml:

actor: UnitTester
bootstrap: _bootstrap.php
modules:
    enabled:
        - Asserts
        - \tests\codeception\Helper\Unit
        - Mockery
additional_paths:
    - src/backend/Model/*/*/Tests/

Example test file \App\Model\DeliveryDate\Calculator\Tests\MyTest:

<?php

declare(strict_types=1);

namespace App\Model\DeliveryDate\Calculator\Tests;

class MyTest extends \Codeception\Test\Unit
{
    public function testWithoutOrderCertificate(): void
    {
        $this->assertFalse(false);
    }
}

Example running test:

$ docker-compose run --rm php-cli vendor/bin/codecept run unit src/backend/Model/DeliveryDate/Calculator/Tests/MyTest.php

OK (1 test, 1 assertion)

Tried adding tests but the current ones are broken. I would be glad to get help writing them.

The idea is nice but all tests are failing. Could you fix them up?
If yes, I have no objections to the idea and implementation

@DavertMik Done.

Wow, that was fast! Thanks!

I just figured out that additional_paths is not the best name here. How about just path: ?
This will make more sense if we provide an option to fully customize paths to tests.

So these options will be possible:

path: .

path: src/backend/Model/*/*/Tests

path:
  - .
  - src/backend/Model/*/*/Tests/

@olegpro what do you think of it? I think it will take minor changes in the code. If you are ok implementing it, I will write documentation.

@DavertMik good idea. I can try to implement.
