Reduce log verbosity

[sjberman]

Problem: NGF control plane logs are very verbose and give more information than is needed at the Info level.

Solution: Reduce many logs to the debug level, including logs from the controller-runtime library. Tests will log at the debug level.

Are these code coverage checks fine to skip?
