+++ This bug was initially created as a clone of Bug #1917605 +++
Description of problem:
Consider a scenario where multiple pods to be external gateways for pod such as:
pod A----OVN--eth0 ----------- External GW Pod1 (188.8.131.52)
|----- External GW Pod2 (184.108.40.206)
|------ cluster default gateway (220.127.116.11)
pod A now has 2 ecmp routes to 18.104.22.168, and 22.214.171.124. Now, we delete External GW Pod1. pod A should still use 126.96.36.199 as its only other ECMP gateway. Instead, we see that deleting External GW Pod1, results in a delete for the ovn_cluster_router policy for this pod A. This causes traffic from pod A to now go via the default cluster gateway (188.8.131.52) .
