With I108242ca9f27c9ec47959ce7615bc7d84cae014b, the last bit from neutron.openstack.common was removed, and with it, all incubator code that could be used by subprojects. It's time to remove the warning on how to properly use incubator. Also removed neutron/openstack directory that is now unused. Change-Id: I0a0744fe68588bd5e3966b7c2457b56583231f42
