[gnome-settings-daemon/docking-stations] Add gnome_settings_session_get_upower_client()

[Federico Mena Quintero <federico src gnome org>]

commit a6d232b4696542ff221413dd15343e78a9e79556
Author: Federico Mena Quintero <federico gnome org>

    Add gnome_settings_session_get_upower_client()
    
    Similar to how gnome_settings_session_get_screen() is used to share a single
    GnomeRRScreen across the plugins, we now share a single UpClient for power-related
    plugins.  In particular, this will let us simplify the code that deals
    with closing the laptop's lid in the power and xrandr plugins.
