Is your feature request related to a problem? Please describe.

I'm trying to graph the cpu and ram usage of my containers and group/sum it by compose project.
For instance, I have a "auth" compose project with 2 containers in it, authelia and redis, I'd like to be able to make a graph and group by this.
I was doing this already with cadvisor that exposes for each container metric a container_label_com_docker_compose_project value.

Describe the solution you'd like

for each metric, expose the value of the docker label com.docker.compose.project as container_label_com_docker_compose_project

Describe alternatives you've considered

keep using cadvisor ;)

My bad, only needed to add

container_labels_to_metric_labels:
  com.docker.compose.project: container_label_com_docker_compose_project

to the reciever config
