[Openstack] [horizon] Weird behaviour of 'user_home' and 'default_dashboard" paramenters in HORIZON_CONFIG

Hi Timur,

You have correctly analyzed the current behavior.  And it is confusing.  In our implementation, 
we have implemented a user_home method that uses the "default_dashboard" to give the user 
a default dashboard.

Now the question is of course, should that be the default behavior for Horizon.  I would argue yes.
The default behavior will need to change, if the upcoming Information Architecture proposals
yield changes as I expect them to.  But there's no reason we couldn't fix this behavior now.

I've a bit of debugging and it seems that get_user_home from > /usr/share/openstack-dashboard/openstack_dashboard/views.py is called (Horizon installed on Ubuntu).
