Authenticating with Azure AD credentials?

Is it possible to authenticate with Active Directory credentials?

I've been trying to work out how to do this but haven't had any luck yet.

This PR seems to add support for it, but it's not documented how to use it anywhere: https://github.com/Azure/azure-storage-ruby/pull/153

I tried copying the code from the test, which uses ADAL, but the gem doesn't seem to install properly because the ADAL gem seems to be dead and bugged: https://github.com/AzureAD/azure-activedirectory-library-for-ruby/issues/44

Is there any other way to authenticate using AD credentials?
