Fill ServiceProvider with registering things on package creation

[baltun]

It would be better if on creation ServiceProvider will be filled with registering code for views, migrations, routes and so on (some of these abilities could be commented to make an ability to developer to uncomment to begin to use it

I'd not want to add commented code to the ServiceProvider. Instead we could look into providing additional options for the make:package command and based on the used options we could then generate code within the ServiceProvider

// creating a package with `resources/views`, `config/package_config_name`, `database/migrations/`
// and the corresponding code within the service provider to load them
php artisan make:package --views --config=package_config_name --migrations --routes

// doing all the above
php artisan make:package --all
