Groups: Add GetTransitiveMembers

[antonjah]

This PR extends the project to include transitive listing of group members as msgraph.User. The addition of this method should not be confused with ListTransitiveMembers as it returns a *[]string, which forces the user to first list, and then get each individual member by ID.

More information about the transitiveMembers endpoint can be found here

Thanks for this @antonjah! I'll happily merge this, but please note that I am going to deprecate this project very soon. We (HashiCorp) recently released a Microsoft Graph SDK that is now being used exclusively in the Terraform AzureAD provider instead of this SDK.

I encourage you to take a look at https://github.com/hashicorp/go-azure-sdk/tree/main/microsoft-graph and consider migrating your project. Many of the same paradigms have been implemented in the new SDK, with many improvements, and because the new SDK is auto-generated, it has massively more coverage.

For this use case, the new SDK has a ListTransitiveMembers() method in the microsoft-graph/users/stable/transitivemember package, which returns a []DirectoryObject - which itself is an interface with automatic type discrimination, so you can retrieve users, groups, service principals etc in the same request.

I will definitely look into that, thanks! :-)

We were trying to migrate from the official(?) msgraph-sdk-go library since it was a pita to work with because of it being generated and probably being the largest go project I have ever seen, leaving us with really bad compile times without a cache available, and very large binaries. Hoping this is something that the above mentioned project can solve.

Again, thanks.
