[release-1.16] Reduce mt-broker-controller memory usage with namespaced endpoint informer #8422

Conversation

This is an automated cherry-pick of #8418

Reduce `mt-broker-controller` memory usage with namespaced endpoint informer.

…ormer

Currently, the mt-broker-controller is using a cluster-wide endpoints
informer but it actually only uses endpoints in the "SYSTEM_NAMESPACE".

Using the namespaced informer factory ensures that the watcher
is only watching endpoints in the `knative-eventing` (also known as
`SYSTEM_NAMESPACE`) namespace.
