[2.0][Bugfix][DependencyInjection] added the ability to use dot and single quotes in the keys and values

Bug fix: yes
Feature addition: no
Backwards compatibility break: no
Symfony2 tests pass: yes
Fixes the following tickets: -

We can not set a specific combination of dots and single quotes in the values ​​and keys of the arguments. I.E.

```xml
<?xml version="1.0" ?>
<container xmlns="http://symfony.com/schema/dic/services"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd">
  <services>
    <service id="key_escaper" class="MyNamespace\MyClass">
        <call method="setCollection">
          <argument type="collection">
            <argument key="only dot">.</argument>
            <argument key="concatenation as value">.''.</argument>
            <argument key="concatenation from the start line">''.</argument>
            <argument key=".">is the same problem for the keys?</argument>
          </argument>
        </call>
      </service>
  </services>
</container>
```

As a result we have such a dump:

```php
<?php

class appDevDev_formapro1DebugProjectContainer extends Container
{
  protected function getKeyEscaperService()
  {
      $this->services['key_escaper'] = $instance = new \MyNamespace\MyClass();

      $instance->setCollection(array('only dot' => , 'concatenation as value' => '.\'\, 'concatenation from the start line' => '\'\,  => 'is the same problem for the keys?'));

      return $instance;
  }
}
```
Added `group_by` to EntityType
