Cause:
All OVN router policies were accidentally being removed for a pod anytime one of its external gateways was removed.
Consequence:
When scaling down a pod that had multiple external gateways, the pod would no longer send egress traffic to any of the still available external gateways. Instead it would send its egress cluster traffic to the default gateway of the node.
Fix:
When external gateways are scaled down, only remove a pods logical_router_policy on ovn_cluster_router when it has no external gateways left.
Result:
Pods now work correctly with external gateways when scaling down. Egress traffic is still sent to the remaining available external gateways and not to the node's default gateway.
