This PR adds command lazy-loading support to the console, based on PSR-11 and DI tags.
(https://github.com/symfony/symfony/issues/12063#issuecomment-57173784)
Commands registered as services which set the `command` attribute on their `console.command` tag are now instantiated when calling `Application::get()` instead of all instantiated at `run()`.
__Usage__
```yaml
app.command.heavy:
tags:
- { name: console.command, command: app:heavy }
```
This way private command services can be inlined (no public aliases, remain really private).
With console+PSR11 implem only:
```php
$application = new Application();
$container = new ServiceLocator(['heavy' => function () { return new Heavy(); }]);
$application->setCommandLoader(new ContainerCommandLoader($container, ['app:heavy' => 'heavy']);
```
Implementation is widely inspired from Twig runtime loaders (without the definition/runtime separation which is not needed here).
