`cgroup: host` is silently ignored by podman-compose provider

[mp1-tomclancy]

Describe the bug
The service cgroup option (see https://docs.docker.com/reference/compose-file/services/#cgroup) is ignored by podman-compose

To Reproduce

compose.yml:

services:
  test:
    image: docker.io/library/busybox:1.37.0
    container_name: cgroup-test
    command: sleep infinity
    privileged: true
    cgroup: host

Run with docker-compose:

$ PODMAN_COMPOSE_PROVIDER=docker-compose podman compose up -d
...
$ podman inspect cgroup-test | jq '.[0].HostConfig.CgroupMode'
"host"
$ PODMAN_COMPOSE_PROVIDER=docker-compose podman compose down
...

Run with podman-compose:

$ PODMAN_COMPOSE_PROVIDER=podman-compose podman compose up -d
...
$ podman inspect cgroup-test | jq '.[0].HostConfig.CgroupMode'
"private"
$ PODMAN_COMPOSE_PROVIDER=podman-compose podman compose down
...

Expected behavior

The container should be created in the host's cgroup namespace (like docker-compose)

Actual behavior

The container is created in an isolated cgroup namespace

Environment:

$ podman-compose version
podman-compose version 1.5.0
podman version 5.8.1

Additional context

I'm using a Lima VM with the podman-rootful template, in order to do integration testing against k0s.
