pkg/operator/utils: Push diff down to the debug level

I think it's worth addressing hotlooping issues, and that they'll be
rare enough that we don't have to worry too much about the log level
of the diff.  But Jeremiah is concerned about log volume, and we do
have a hot loop in [1] today that hasn't been fixed yet.  This commit
pushes the diff-rendering down to the debug level.  Users can set
cloudcredentials.operator.openshift.io spec.logLevel to Debug or
higher to see the diff.
