    Improve nova-ironic cellv2 discovery

    Use the existing nova-compute cellv2 discovery logic for nova-ironic too, now
    that we have the --by-service flag.
    The nova_api_discover_hosts.sh script will now wait (up to 10 minutes) for all
    nova-compute and nova-ironic services to register, then run host discovery
    with --by-service to create host mappings for all services. We no longer need
    ironic nodes to be deployed on the nova-ironic services for discovery to work.
    We also no longer need to enable the priodic job.
