[IMPROVEMENT]Use CD/CI Variables for Deployer

[plexmaniax]

Am I right, there is no option to use CD/CI Variables in deployer, we always need a file like project.yaml where secrets are saved in plain text?

I'll tried it this way

host('staging')
->set('labels', ['stage' => 'staging'])
->set('hostname', getenv('SSH_HOST'))
->set('remote_user', getenv('SSH_USER'))
->set('http_user', getenv('SSH_USER'))
->set('deploy_path', getenv('DEPLOY_PATH'))
->set('port', (int) getenv('SSH_PORT'))
->set('bin/php', function() {
return getenv('REMOTE_PHP_BINARY');
})

But it seems a little bit unhandy. Is there a way to reuse CD/CI Variables not only as DOTENV ?
