The tests against specific Symfony versions are now running only for a single PHP version to limit the number of jobs in the build matrix. They are also installing the full Symfony repo to be sure that all components are actually at the specified version without the need to require each of them explicitly.
Fixed the retrieval of the validation MetadataFactory

The service is private so getting it from the container get() method is invalid and it does not work anymore in Symfony 2.5 because the service gets inlined.

Unified data types [actualType and subType]

This is the result of https://github.com/nelmio/NelmioApiDocBundle/issues/410.

This PR aims to provide a uniform way of declaring data-types of parameters for
parsers and handlers to follow. In turn, this would allow formatters to
determine data-types in a cleaner and less volatile manner. (See use-case that
can be improved with this PR:
https://github.com/nelmio/NelmioApiDocBundle/blob/master/Formatter/AbstractFormatter.php#L103)

This is possible by the addition two properties to each property item in
`response`, and `parameters` fields in each API endpoint produced by the
`ApiDocExtractor`:

* `actualType` Contains a value from one of the `DataTypes` class constants.

* `subType` Can contain either `null`, or any other `DataTypes` class constant.
This is relevant when the `actualType` is a `DataTypes::COLLECTION`, wherein
`subType` would specify the type of the collection items. It is also relevant
when `actualType` is a `DataTypes::MODEL`, wherein `subType` would contain an
identifier of the model (the FQCN or anything the parser would wish to specify)

Examples:

```php

array(
    'id' => array(
        'dataType' => 'integer',
        'actualType' => DataTypes::INTEGER,
        'subType' => null,
    ),
    'profile' => array(
        'dataType' => 'object (Profile)',
        'actualType' => DataTypes::MODEL,
        'subType' => 'Foo\Entity\Profile',
        'children' => array(
            'name' => array(
                'dataType' => 'string',
                'actualType' => DataTypes::STRING,
                'subType' => null,
             ),
            'birthDate' => array(
                'dataType' => 'date',
                'actualType' => DataTypes::DATE,
                'subType' => null,
            ),
        )
    ),
    'languages' => array(
        'dataType' => 'array of strings',
        'actualType' => DataTypes::COLLECTION,
        'subType' => DataTypes::STRING,
    ),
    'roles' => array(
        'dataType' => 'array of choices',
        'actualType' => DataTypes::COLLECTION,
        'subType' => DataTypes::ENUM,
    ),
    'groups' => array(
        'dataType' => 'array of objects (Group)',
        'actualType' => DataTypes::COLLECTION,
        'subType' => 'Foo\Entity\Group',
    ),
    'profileRevisions' => array(
         'dataType' => 'array of objects (Profile)',
         'actualType' => DataTypes::COLLECTION,
         'subType' => 'Foo\Entity\Profile',
    ),
    'address' => array(
        'dataType' => 'object (a_type_a_custom_JMS_serializer_handler_handles)',
        'actualType' => DataTypes::MODEL,
        'subType' => 'a_type_a_custom_JMS_serializer_handler_handles',
    ),
);
```

When a formatter omits the `dataType` property or leaves it blank, it is
inferred within `ApiDocExtractor` before everything is passed to formatters.
