    Pass '--dhcp-authoritative' option to dnsmasq

    When dnsmasq is restarted, it forgets about all leases (since it runs
    with leasefile-ro option). When client tries to renew its lease, dnsmasq
    sends DHCPNAK reply with message "lease not found". Then client shuts
    down the network and re-request lease from DHCP server (and gets exactly
    same IP address). There's a small network downtime which affects
    services, like zookeeper, running in VMs.
