Export traces and logs from Netbird

[kKdH]

We are interested in the logs and traces of netbird. Therefore the configuration of Netbird should be adjusted to export these information to the OpenTelemetry collector.

@reimarstier please add some infos about required Netbird configuration

Netbird exposes a metrics endpoint here: https://github.com/netbirdio/netbird/pull/517. Logs may need an exporter on the container itself.

Configuration parameters of netbird management service are the following:

root@da63af8bb856:/# /go/bin/netbird-mgmt management --help | grep metrics
      --disable-anonymous-metrics           disables push of anonymous usage metrics to NetBird
      --metrics-port int                    metrics endpoint http port. Metrics are accessible under host:metrics-port/metrics (default 8081)

If not disabled, the netbird management service exposes a metrics endpoint here: http://netbird-management:8081/metrics
