Currently we have a convenience command that allows you to easily create AAD app registration with a set of predefined settings. We should add support to let users create AAD app registrations based on the manifest they get from the Azure portal. That way, they can create and configure the app they need in the portal, and get its manifest for provisioning in other environments.

We can implement it by extending the existing aad app add command with a new option, named manifest which takes the manifest contents (which can also be passed directly from a file using the @-token) and uses it to configure the created app.
