This PR add a new env processor `url` to convert an URL (or DSN) into an array.
The main goal is to simplify the project configuration and reduce the number of env variable when working with bundle which are not able to deal with DSN
(pick some random project in symfony/recipes-contrib: https://github.com/symfony/recipes-contrib/blob/master/facile-it/mongodb-bundle/0.6/manifest.json or https://github.com/symfony/recipes-contrib/blob/master/wouterj/eloquent-bundle/1.0/manifest.json)
```yaml
# before

# after
MONGODB_DSN=mongodb://localhost:27017/symfony
mongo_db_bundle:
data_collection: '%kernel.debug%'
clients:
default:
hosts:
- { host: '%env(key:host:url:MONGODB_DSN)%', port: '%env(key:port:url:MONGODB_DSN)%' }

connectTimeoutMS: 3000
connections:
default:
database_name: '%env(key:path:url:MONGODB_DSN)%'
```
Added also a `query_string` processor to parse query string
```
DATABASE_DSN=mysql://localhost/db?charset=utf8
foo:
bar:
charset: '%env(key:charset:query_string🔑query:url:DATABASE_DSN)%'
```

[DependencyInjection] Add ability to define an index for service in an injected service locator argument
| Q | A

It's more or less the same thing then the PR #30257 but for a service locator argument
Add a simple way to specify an index based on a tag attribute to simplify retrieving a specific service when injecting a service locator as argument into services, but also a way to fallback to a static method on the service class.
Yaml:
```yaml
services:
foo_service:
class: Foo
tags:
- {name: foo_tag, key: foo_service}
foo_service_tagged:
class: Bar
arguments:
- !tagged_locator
tag: 'foo_tag'
index_by: 'key'
default_index_method: 'static_method'
```
XML:
```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/serviceshttp://symfony.com/schema/dic/services/services-1.0.xsd">
<services>
<service id="foo" class="Foo">
<tag name="foo_tag" key="foo_service" />
</service>
<service id="foo_tagged_iterator" class="Bar" public="true">
<argument type="tagged_locator" tag="foo_tag" index-by="key" default-index-method="static_method" />
</service>
</services>
</container>
```
PHP:
```php
// config/services.php
use Symfony\Component\DependencyInjection\Argument\TaggedIteratorArgument;
use Symfony\Component\DependencyInjection\Argument\ServiceLocatorArgument;
$container->register(Foo::class)
->addTag('foo_tag', ['key' => 'foo_service']);
$container->register(App\Handler\HandlerCollection::class)
// inject all services tagged with app.handler as first argument
->addArgument(new ServiceLocatorArgument(new TaggedIteratorArgument('app.handler', 'key')));
```
Usage:
```php
// src/Handler/HandlerCollection.php
namespace App\Handler;
use Symfony\Component\DependencyInjection\ServiceLocator;
class HandlerCollection
{
public function __construct(ServiceLocator $serviceLocator)
{
$foo = $serviceLocator->get('foo_service'):
}
}
```

Nullable environment variable processor

Hey there,
Because environment variables are strings by design, empty environment variables are evaluated to `""` by default.
In the same way, `MY_ENV_VAR=null` will be evaluated to `"null"`, as a string.
What I suggest is to allow some environment variables to be evaluated to `null` (the real one) when their strings are _blank_ or equal _null_, _Null_ or _NULL_.
This can be easily done through a new `nullable` processor:
```bash
# .env
API_KEY=
```
```yaml
# config/services.yaml
services:
FooService:
arguments:
$apiKey: %env(nullable:API_KEY)%
```
```php
# src/Services/FooService
namespace App\Services;
final class FooService
{
/**
* @var string|null
*/
private $apiKey;
/**
* FooService constructor.
*/
public function __construct(?string $apiKey)
{
$this->apiKey = $apiKey;
}
public function doSomething()
{
// Free plan
if (null === $this->apiKey) {
// ...
}
}
}
```
That's an example that comes to my mind but there can be many others.
This can also help in using null coalesce operators in constructors instead of checking if a string equals `""` (which is very PHP4 style).
Of course it can be used in conjunction with other types, i.e. `%env(float:nullable:SOME_OPTIONAL_FLOAT_ENV_VAR)%`.
What do you think?

Because that name makes things harder to understand now.
This uses exactly the same BC layer logic as the one we have for the renaming of DefinitionDecorator to ChildDefinition.
