Cause
Nova switched to use oslo.concurrency and removed nova/openstack/common/lockutils.py (which was still in use by ironic)

    Switch to oslo.concurrency

    Nova has removed nova/openstack/common/lockutils.py and switched to
    oslo.concurrency so we can no longer import lockutils from the nova
    tree.

    Make the same switch in the ironic tree.

seems like nova-compute also has the problem. nova-compute always can not start because of below error

$ sudo start-stop-daemon --start -c nova --exec /opt/stack/venvs/nova/bin/nova-compute -- --config-dir /etc/nova --config-dir /etc/nova/compute

I think this was the original error, was this with a ironic from after the fix was committed ?
