    TabGroup: Make tabs pluggable via horizon plugin config

    This commit enhances django tab implementation to allow horizon plugins
    to add tabs to a tab group in other repository like the main horizon repo.
    New setting "EXTRA_TABS" is introduced to the horizon plugin 'enabled' file.
    To this aim, the tab group class looks up HORIZON_CONFIG['extra_tabs']
    with its class full name and loads them as extra tabs if any.
    HORIZON_CONFIG['extra_tabs'] are populated via horizon plugin settings.

    This commit moves update_settings in openstack_dashboard.test.helpers
    to horizon as I would like to use it in a new horizon unit test.
