feat: Allow run-task command to configure server / build stage

[Fgruntjes]

This allows the run-task command to deploy some file to a server for example:

<?php

namespace Hypernode\DeployConfiguration;

use function Deployer\run;
use function Deployer\task;
use function Deployer\upload;

$configuration = new Configuration();

$productionStage = $configuration->addStage('production', '****');
$productionStage->addServer('****.hypernode.io');

task('app_deploy', static function () {
    $imageTag = getenv('IMAGE_TAG');
    run('mkdir -p /data/web/auth_gateway');
    upload('docker-compose.yaml', '/data/web/auth_gateway/docker-compose.yaml');
    run("echo '$imageTag' > /data/web/auth_gateway/.env");
    run('cd /data/web/auth_gateway && docker-compose up -d');
});

$configuration->addDeployTask('app_deploy');

return $configuration;
