Oh, I actually should have thought about it. So if you'll precreate the
network, subnet and a KuryrNet Custom Resource [1] it should actually
work. The definition of KuryrNet can be find here [2], fields are
pretty self-explanatory. Please note that you also need to link
KuryrNet to the namespace by adding an annotation to the namespace:

 "openstack.org/kuryr-net-crd": "ns-<namespace-name>"

Also, just for safety, make sure the KuryrNet itself is named "ns-
<namespace-name>" - I'm not sure if some code isn't looking it up by
name.

Please note that this was never tested, so maybe there's something I
don't see that might prevent it from working.
