Description of problem:
In ACM 2.11.5, if a user has a very large cluster that have a lot of operators running, there is a chance where the MCH operator could fail to list/get ClusterServiceVersion resources. This is happening because the client-go that the MCH operator is utilizing is having issues with caching the amount of resources available.
The multiclusterhub-operator logs are filled with below errors: 2025-02-13T05:55:07.111684784Z E0213 05:55:07.111672 1 reflector.go:147] pkg/mod/k8s.io/client-go@v0.29.3/tools/cache/reflector.go:229: Failed to watch *v1alpha1.ClusterServiceVersion: failed to list *v1alpha1.ClusterServiceVersion: stream error when reading response body, may be caused by closed connection.
