Set openstack_old_version to openstack version by default

openstack_old_version is used only during upgrade/update procedure.
By default openstack_old_version should be the same as openstack_version
and not hardcoded. Currently it is always ocata, but with this patch
it can be easily overriden from cluster level. The same also is
applicable for Gnocchi.
