Following a recent support ticket I had found that it was not obvious how to configure the settings for a <kendo-popup> instance.

Controls such as the <kendo-dropdownlist>, which uses a <kendo-popup> internally, expose a `popupSettings` property which allows easy and declarative configuration of behavious such as the `appendTo`. With a native <kendo-popup> you do not have the ability to set an `appendTo` declaratively, you have to inject the PopupService into the code behind and negotiate providing a ViewContainerRef instance from another component. 

To give greater consistency and to enhance developer ease of use it would be nice if the <kendo-popup> component exposed a PopupSettings (https://www.telerik.com/kendo-angular-ui/components/dropdowns/api/popupsettings) object in the same manor as the dropdowns.
