* change to klog/v2 * add logfilepath opt in helm chart * replace klog.InfoF with klog.InfoS and improve messages Remove string formatting from log message, improve messages in klog.InfoS and use lowerCamelCase to fmt Name arguments in klog.InfoS * fix klog.Error for expected errors (errors that can happen during routine operations) use klog.InfoS and pass error in err key instead. * use klog.KObj and klog.KRef for Kubernetes objects ensure that kubernetes objects references are consistent within the codebase * enable set logdebug level * add log-file-max-size
