Feature Request: Add a cmdlet to gather the Azure AD role

[hausec]

Description of the new feature

Similar to the Get-AzureADDirectoryRole cmdlet in AzureAD module, it will gather the users that are in a role, OR also gather the AAD role when using Get-AzADUser

Proposed implementation details (optional)

Thanks reporting. We will consider this feature. In general, Az PowerShell only covers the basic functions of Azure Ad. We suggest user to try the AzureAD for advance features.
