Send Logs To Loki while Still Preserving Console Output

[BbBaboo42]

What feature do you want to see added?

In the Grafana Visualization Observability Backend, you currently must choose between:

1. Don't store pipeline logs in Loki
2. Store pipeline logs In Loki and visualize logs exclusively in Grafana (logs no longer visible through Jenkins screens)

While I do want the logs to be sent to Loki, I still need for the Console Output to exist, for other Jenkins plugins such as BlueOcean, Pipeline Overview and others.

I now see that configuring otel.logs.mirror_to_disk=true in the plugin configuration does achieve my goal. However, It is very strange that for me to collect the build logs to loki, I have to add a Grafana Visualization Backend, and under its advanced option choose: Store pipeline logs in Loki and visualize logs exclusively in Grafana (logs no longer visible through Jenkins Controler)

Which I then supposed to cancel out with the configuration otel.logs.mirror_to_disk=true

PR above is about mirroring pipeline logs in Jenkins and Loki. A subsequent improvement would be to display in Jenkins logs stored in Loki so we no longer need to mirror logs in order to display logs in Jenkins GUIs
