[Bug 1324119] [NEW] External network that is not "Shared" still can be set as gateway for any(!) tenant's router in OpenStack Dashboard (Horizon)

 

Public bug reported:

I have an Icehouse 2014.1 installation on Ubuntu 14.04 LTS.

I have configured 2 external networks. The first one (External) is
Shared and so can be used by any tenant. The second (misc) is not Shared
and was created only for one specific tenant. Still all the rest tenants
can set it as gateway for their routers and allocate and assign floating
IPs from it to their instances in OpenStack Dashboard (Horizon). It is
also seen on any tenant's network topology.
