Add ContainerCli parameter, default to docker. Possible values: podman/docker (default). Deprecate DockerAdditionalSockets so it does nothing for podman. Nested podman CLI replaces docker sockets. Only bind mount /var/lib/openstack for the neutron/ovn agents for docker. Support debug messages for Neutron/OVN wrappers controled via NeutronWrapperDebug and OWNWrapperDebug (defaults to False). Or globally controlled by Debug. Make the wrapper containers managed by its parent processes and not exited/removed forcibly, when the parent container restarts. Background for podman CLI replacing the docker socket: We'll use 'nsenter -m -n -p -t 1 podman' in wrappers to execute podman in the same namespaces as on the host and to NOT bind-mount world for that, like: - /sys/fs/cgroup:/sys/fs/cgroup - /run/libpod:/run/libpod - /run/containers:/run/containers - /run/runc:/run/runc - /run/runc-ctrs:/run/runc-ctrs - /var/lib/containers:/var/lib/containers - /etc/containers:/etc/containers:ro - /usr/bin/podman:/usr/bin/podman:ro - /usr/bin/runc:/usr/bin/runc:ro - /usr/libexec/podman/conmon:/usr/libexec/podman/conmon:ro - /usr/lib64/libseccomp.so.2:/usr/lib64/libseccomp.so.2:ro ... We cannot use chroot /host instead as there is more bind-mounts to use outside of the /host chroot. Maybe varlink is a good replacement for all of that, but it's not there yet.
