Need functional API samples test for os-server-groups GET with all_projects parameter

[Matt Riedemann]

The os-server-groups API request can have an 'all_projects' query parameter:

https://github.com/openstack/nova/blob/master/nova/api/openstack/compute/server_groups.py#L118

From what I can tell we don't test that anywhere in the nova functional API tests tree. It's definitely not tested in Tempest.
