[3.x] Define services in more convenient and readable way

[voronkovich]

Summary of Changes

This PR introduces a new container method def() which returns a special resource builder allowing to configure service in a more convenient way using fluent interface:

$container->def(CacheControllerFactoryInterface::class)
    ->shared()
    ->protected()
    ->lazy(CacheControllerFactory::class)
    ->factory(
        function (Container $container) {
            return new CacheControllerFactory();
        },
    )
    ->aliases([ 'cache.controller.factory', CacheControllerFactory::class ])
    ->tags([ 'cache_controller' ])
    ->end();
