set controller-runtime logger to a null logger

Browse Source 
This is required because controller-runtime expects its consumers to
set a logger through log.SetLogger within 30 seconds of the program's
initalization. If not set, the entire debug stack is printed as an
error. Ref: https://github.com/kubernetes-sigs/controller-runtime/blob/ed8be90/pkg/log/log.go#L59
Since we have our own logging and don't care about controller-runtime's
logger, we configure it's logger to do nothing.
