Create missing directories before mounting them

When deploying with podman, we need to create directories if they don't
exist before trying to mount them later when containers are starting.
Otherwise, podman fails with this kind of error:
error checking path \"/etc/iscsi\": stat /etc/iscsi: no such file or directory"
