EDS updates take longer (5-6 seconds) rather than instantaneous

[saiskee]

Gloo Edge Version

1.12.x (latest stable)

Kubernetes Version

1.23.x

Describe the bug

• 1.12.8
  • we are able to kubectl rollout a service and the endpoints propogate instantly to envoy, which is desirable.
• 1.12.15
  • after this fix went in (https://github.com/solo-io/gloo/pull/7104), endpoints now take longer to get updated in envoy, minimum 6 seconds and max around 20 seconds

Steps to reproduce the bug

unable to reproduce locally, trying to reproduce in customer env

Expected Behavior

EDS updates should very fast (<1 second) as has been seen in gloo 1.12.8. As soon as we upgrade the gloo pod to 1.12.15, the EDS updates get slow.
