ADD_INSTALLED_APPS in _80_nfv.py file

[Yimeng]

For the file "tacker_horizon/enabled/_80_nfv.py", in "ADD_INSTALLED_APPS", the first item "tacker_horizon" should be removed. Otherwise it will cause problem of Horizon in loading related plugins. For example, the "Image" and "Instance" tab doesn't work correctly.

Hi @Yimeng, that's correct I agree with you. And the horizon workflows are also not working properly. But I couldn't get the reason why 'tacker_horizon' is throwing tha error.

Hi, also our devstack install was affected by this bug, after we added Tacker.

I confirm that the proposed workaround of removing "tacker_horizon" in "tacker_horizon/enabled/_80_nfv.py" makes the Images interface working again.

    Remove tacker-horizon to make this JS path right

    tacker_horizon in /dashboard/i18n/js/horizon+openstack_dashboard+
    mistraldashboard+tacker_horizon+tacker_horizon.openstack_dashboard.
    dashboards.nfv/ is causing the file not found bug.

    Remove it from _80_nfv.py will get the right path.
