Support for the current version of UMA

[davidtnorth]

Currently, I can do this:

Realm.objects.first().client.uma1_api_client

I'd like to be able to do this:

Realm.objects.first().client.uma_api_client

i.e. use UMA as supported in Keycloak 4.x and above. The necessary hooks are there in the underlying Keycloak admin client library; would you be open to a patch to add the support in the Django side?
