Comment 6 for bug 1759839

I checked our docs and it looks like we have port 8780 in the OpenSUSE documentation:

https://github.com/openstack/nova/blob/20bc0136d0665bafdcd379f19389a0a5ea7bf310/doc/source/install/controller-install-obs.rst

And we have port 8778 in the RDO and Ubuntu docs:

https://github.com/openstack/nova/blob/20bc0136d0665bafdcd379f19389a0a5ea7bf310/doc/source/install/controller-install-rdo.rst
https://github.com/openstack/nova/blob/20bc0136d0665bafdcd379f19389a0a5ea7bf310/doc/source/install/controller-install-ubuntu.rst

I agree that we should be consistent in our docs.

As for the use of port 8780 in devstack, Chris says it's no longer used, so I think it could be removed:
