38% of pods on my cluster are event listeners, too many for AWS EKS, Tekton should not stress pod limits

[doctorpangloss]

The event listener pods eat up a lot of precious pod limits on AWS EKS.

On my cluster, 41 out of 106 pods are event listener pods. So just to host these pods, I need an extra m6a.xlarge (58 pod limit).

The event listener resource should probably be satisfied by a single controller instead of one process per event listener.

@doctorpangloss Have you tried using Multi Tenant EventListener? https://github.com/tektoncd/triggers/tree/main/examples/v1beta1/namespace-selector
