[9.18] Implemented with_labels_details parameter

[rickkuilman]

I've implemented the with_labels_details parameter on the issues resource according to the GitLab.com Issues API docs.

It adds a more detailed version of the labels attribute like this:

// Retrieve all issue
$this->gitLabManager->issues()->all(1);

/**
 *  "labels" => array:1 [▼
 *      0 => "Bug"
 *      1 => "Approval"
 *  ]
 */

// Retrieve all issues, with more detailed version of the labels attribute
$this->gitLabManager->issues()->all(1, [
    'with_labels_details' => true,
]);

/**
 *  "labels" => array:2 [▼
 *    0 => array:5 [▼
 *      "id" => 3266
 *      "name" => "Bug"
 *      "color" => "#CC0033"
 *      "description" => "It's bug, not a feature"
 *      "text_color" => "#FFFFFF"
 *    ],
 *    1 => array:5 [▼
 *      "id" => 3280
 *      "name" => "Approval"
 *      "color" => "#35824F"
 *      "description" => "Ready for approval"
 *      "text_color" => "#FFFFFF"
 *    ]
 *  ]
 */

Happy #hacktoberfest everybody!

Can you update the tests?

Ping @rickkuilman. Do you plan on completing this PR please?

I'm curious how the boolean values should be validated. I've seen different patterns across this library, nothing sticks.

1. no validation at all:

   $resolver->setDefined('with_labels_details')

2. input boolean, output boolean like here:

      $resolver->setDefined('with_labels_details')
         ->setAllowedValues('with_labels_details', [true, false]);

3. input boolean, output string:

      $booleanNormalizer = function (Options $resolver, $value) {
         return $value ? 'true' : 'false';
      };
      $resolver->setDefined('first_parent')
         ->setAllowedTypes('first_parent', 'bool')
         ->setNormalizer('first_parent', $booleanNormalizer);

Thanks for starting work on this @rickkuilman. Are you able to finish this PR? 🚀

input boolean, output string

@glensc This is the correct one. The rest of the code is meant to also look like that.

This has now been implemented on 9.18. :)
