🐛 Updates for the controller manager to watch everything

[waltforme]

Summary

This PR increases the memory limit of the controller manager, and adjusts the verbosity levels for the logging messages from the event handlers.

Changes in this PR are built into quay.io/junatibm/controller-manager:1711835357. I tested the image, with the increased memory limit, in the same environment as #1990. The controller ran for minutes without OOMKilled:

I would make these V levels even higher. At least 4, maybe 5.
