README_OPENSTACK.md only describes how to configure OpenStack with ONOS.
In fact, all the things to do that are related with ONOS are written in another file.
Please, in README_OPENSTACK.md write that it is possible to install OS both with ONOS and ODL, and that, while instructions about ODL are in the current file, ONOS is instead described into another file (put then the pointer).
