Run single container as root, keep others rootless

**Is your feature request related to a problem? Please describe.**
One of my containers needs root access, because it calls the `perf_event_open` syscall. Therefore it needs to be executed rootfull with `sudo podman run` (notice the `sudo`). Consequently it also needs to be executed as `sudo podman-compose up`. But if I understand it correctly that will put all the containers in root mode, while I just need it for one of them.

**Describe the solution you'd like**
I'd like to specify the container to be put in root mode and keep the other containers rootless. I can imagine it either as an argument to `podman-compose`, e.g. `podman-compose --root-mode container_name`, or as a key in the `compose.yml`.

**Describe alternatives you've considered**
Starting it with `sudo podman-compose up` works, but I'd prefer rootless as much as possible.

Maybe there is an option already, but I did not find one.
