Metrics collection

The Containerd sensor automatically start collecting metrics using ctr metrics. It requires a ctr version higher than 1.2.0. If an older version of ctr that does not provide the metrics command, the sensor will automatically fallback to getting metrics from the Prometheus endpoint. In this case, in order to enable metrics collection, the metrics address needs to be specified in the Containerd configuration file located in /etc/containerd/config.toml. Restart containerd.service afterwards.
