Get-AzADUser missing properties

## Description of the new feature
I'm attempting to get our team to use azure cloud shell and when attempting to query userinformation we've found get-azaduser to be a fairly worthless command as it doesn't appear to return any information about the user (like department, usage location, office info, or basically any properties on the user).

Hopefully I'm just missing something super obvious, but how are admins supposed to use these new modules if they don't return valuable information or the ability to manage users or is this just completely out of scope for cloudshell?

Thanks!

Start at the Get-AzADUser command entry point and reproduce its current output in Azure Cloud Shell. Compare the returned user information with the requested department, usage location, office information, and other user properties. Done means the supported user properties are available to administrators and the behavior is covered by the project's relevant tests.
