    Do not purge the Ironic Inspector dhcp-hostsdir

    Since the ironic-inspector service and the dnsmasq
    service for ironic-inspector is running in different
    containters, having the ironic-inspector service
    start/stop the dnsmasq service is non-trivial.

    Using `--pid="host"` and making the containers
    priviligeied seems less than ideal.

    This changes the ironic-inspector configuration so
    that it will no longer purge the dhcp-hosts dir on
    intialization. Purging the directory without also
    restarting (or HUP) the dnsmasq service can cause
    the configuration in the DHCP service to deviate
    from what ironic-inspector intend it to be.
