JSON log format and log verbosity configuration

I could not find anything about it, but is it already possible to configure a _**logging format**_ (`text` | `json` | `console` etc) for:
* `newrelic-logging`
* `nrk8s-kubelet`
* `nri-kube-events`
* `nri-metadata-injection`

and and the _**logging verbosity**_ (`info` | `warning` | `error` etc) for:
* `nrk8s-kubelet`
* `nri-kube-events`
* `nri-metadata-injection`
