Hello;

I write many CLI application, and "single command" in cli application is not so easy to write.
This is why I propose this patch. IMHO, this PR could replaces#9609.

See it in application:

#!/usr/bin/env php<?phprequire__DIR__.'/vendor/autoload.php';useSymfony\Component\Console\Application;useSymfony\Component\Console\Input\InputArgument;useSymfony\Component\Console\Input\InputInterface;useSymfony\Component\Console\Input\InputOption;useSymfony\Component\Console\Output\OutputInterface;(newApplication('echo','1.0.0'))    ->register('echo')        ->addArgument('foo', InputArgument::OPTIONAL,'The directory','foo')        ->addOption('bar',null, InputOption::VALUE_REQUIRED,'Foobar','bar')        ->setCode(function(InputInterface$input,OutputInterface$output) {$output->writeln('start');$output->writeln($input->getArgument('foo'));$output->writeln($input->getOption('bar'));        })    ->getApplication()    ->setUniqueCommand('echo')    ->run();

Some usage:

>(3)[{..}eg/dev/github.com/symfony/symfony](console-one-app) php test.php startfoobar

>(3)[{..}eg/dev/github.com/symfony/symfony](console-one-app) php test.php  "first argument"startfirst argumentbar

>(3)[{..}eg/dev/github.com/symfony/symfony](console-one-app) php test.php  "first argument" --bar="first option"startfirst argumentfirst option
