This enables Azure Government Cloud to work as an OAuth2 provider since
this version refactors out the use of
`https://graph.microsoft.com/v1.0/me` via
https://github.com/RIPGlobal/omniauth-azure-activedirectory-v2/pull/1.

Azure Government Cloud uses `.us` as a suffix, so instead of
`https://graph.microsoft.com` the base URL should be
`https://graph.microsoft.us`. `base_azure_url` needs to be set to
`https://login.microsoftonline.us` as well.

This upgrade requires upgrading the related OmniAuth gems as well. There
are minor changes in those gems.
