[release-4.22] OCPBUGS-85089: Allow OVN-Kubernetes CIDROverlap pathological events

[jcaamano]

OVN-Kubernetes EVPN e2e tests when running in parallel create multiple VTEP resources with the same CIDR. OVN-Kubernetes logs this through events with no further consequence other than reporting the wasteful resource use. When sufficient EVPN e2e tests run in parallel, monitoring pathological event tracker picks this up and fails the job.

https://redhat.atlassian.net/browse/OCPBUGS-85087 will fix the tests to share the same VTEP resource. Until then, add an exception for the event.

(cherry picked from commit e7e6860)

Summary by CodeRabbit

• New Features
  • Added detection for CIDR overlaps between OVN-Kubernetes EVPN CIDRs and VTEP configurations to improve cluster networking validation.

Pipeline controller notification
This repo is configured to use the pipeline controller. Second-stage tests will be triggered either automatically or after lgtm label is added, depending on the repository configuration. The pipeline controller will automatically detect which contexts are required and will utilize /test Prow commands to trigger the second stage.

For optional jobs, comment /test ? to see a list of all defined jobs. To trigger manually all jobs from second stage use /pipeline required command.

This repository is configured in: automatic mode

Walkthrough

A new pathological event matcher OVNKubernetesCIDRsOverlapWithVTEPsEvents is added to detect CIDR overlaps between OVN-Kubernetes EVPN CIDRs and VTEP CIDRs, with pattern matching on "CIDROverlap" reason and "CIDRs overlap with VTEPs" message, referenced to OCPBUGS-84917.
