[Bug 2009883] [NEW] Remote metadata server internal server error

[Peter Sabaini]

Public bug reported:

Getting intermittent issues getting connectivity when spawning
instances. The instance would spawn ok but never leave 'pending' state
from Jujus POV.

On the console I can see it doesn't get a hostname set, and on the
compute host I see these tracebacks, from neutron-ovn-metadata-
agent.log:
