    openvswitch: Use ansible_hostname for system-id

    Currently openvswitch sets system-id based on inventory_hostname, but when
    Ansible inventory contains ip addresses - then it will only take first ip
    octet - resulting in multiple OVN chassis being named i.e. "10".
    Then Neutron and OVN have problems functioning, because a chassis named "10"
    will be created and deleted multiple times per second - this ends up in
    ovsdb and neutron-server processes using up to 100% CPU.

    Adding openvswitch role to ovn CI job triggers.
