When it happens

Trigger: `kops update cluster`/`kops get` on a cluster where the Octavia listener list API returns an error — Octavia endpoint unreachable, 403 on the lbaas API, auth token expired, or catalog missing the octavia service.

Common situations: Octavia not deployed in the cloud/region (no endpoint for load-balancer service); expired OpenStack credentials; network/firewall blocking the API; wrong OS_* region configured.
