Comment 1 for bug 1652076

Looks like problem is in empty feature group list, that comes from GET /api/version.
dpdkovs bond type (that corresponds to enabled DPDK) requires 'experimental' feature group https://github.com/openstack/fuel-web/blob/stable/mitaka/nailgun/nailgun/fixtures/openstack.yaml#L437

We need to check the issue when feature_groups list is not empty and contains 'experimental'.
