That might do what you want (there's equivalents you can do at launch to
specify fixed IP and even MAC if you need to for example on a license
server), but while you'll know the IP in advance it still relies on
OpenStack's DHCP service to get that IP into the VM.  We use this quite a
lot and it works well, is accesable from the the API, CLI and Heat
templates.  We even kludged a little addition to the Horizon launch
workflow (I can provide it as an example but isn't very robust ).

But, if you are  really looking to avoid DHCP (rather than just the dynamic
IP part) you'll need to s things a bit differently.  I've not tried this,
but I think using a 'config drive' and passing in a user data script to
statically configure the interface(s) would be the way to go, note you'll
need cloud-init (or a similar script) in the image to execute the user data
and you can't rely on the metadata service because that relies on the
network being setup so it can reach the metadata server over http.
