    Prevent dnsmasq from reading hosts file

    OpenStack-Ansible configures /etc/hosts with the management IP
    addresses of containers, but dnsmasq gets confused when it sees those
    host names associated with a 10.X address on the lxc bridge. It
    causes lots of errors in the log files like these:

      not giving name hydrogen_rsyslog_container-307df194 to the DHCP
      lease of 10.0.3.196 because the name exists in /etc/hosts with
      address 172.29.239.71

    This patch adds the --no-hosts option for dnsmasq so that it will
    stop reading /etc/hosts and filling up log files.
