[Bug 1868726] [NEW] Unhandled KeyError during subnet creation
Public bug reported:
I'm attempting to use tripleo's network isolation technique [0] on
stable/train, but my undercloud neutron service is failing during subnet
creation for the overcloud with a generic python KeyError:

While I'm not entirely convinced I didn't mis-configure something, the
error bubbled up through neutron's server.log isn't descriptive in what
I did wrong and doesn't seem to be validated by neutron's API layer.

interested in seeing how I'm doing that):
