feat: adding option to select ingress class

[cskiwi]

By default when creating a new app the ingress class is set to the environment value, or when that is not set to nginx. this feature allows this to be loaded via the UI and default to the same behaviour

I think you accidentally copied the app form to the pipelines folder.
