PopupService to Close Popup

[sonnythao]

@bijington I'm thrilled that the new PopupService is in and I've successfully implemented it in my view model to show a popup - but can I use it to close the opened popup in my view model too? Before using this new PopupService, I was opening and closing my loading indicator popup from the popup itself as so:

// Open loading indicator
var loadingIndicatorPopup = new LoadingIndicatorPopup
{
CanBeDismissedByTappingOutsideOfPopup = false
};
Shell.Current.CurrentPage.ShowPopup(loadingIndicatorPopup);
. . . . (other code to run while the popup is opened) . . . .

// Close loading indicator
await loadingIndicatorPopup.CloseAsync();

I opted to use the new PopupService to allow me to more easily write unit tests for my view model.

Currently this is not possible, however I believe @VladislavAntonyuk did also suggest we should provide this functionality. I shall write up a proposal to cover this functionality

Here is the proposal: #1530
