ceph-osd: check container engine rc for pools

When creating OpenStack pools, we only check if the return code from
the pool list command isn't 0 (ie: if it doesn't exist). In that case,
the return code will be 2. That's why the next condition is rc != 0 for
the pool creation.
But in containerized deployment, the return code could be different if
there's a failure on the container engine command (like container not
running). In that case, the return code could but either 1 (docker) or
125 (podman) so we should fail at this point and not in the next tasks.
