If an user is trying to configure a dhcp neetwork settings, it is not
possible to change the leasetime of a range or a host entry. This is
available using dnsmasq extra options, but they are associated with
dhcp-range or dhcp-hosts fields. This patch implements a leasetime for
range and hosts tags. They can be defined under that settings:
<dhcp>
<range ...>
<lease/>
</range>
<host ...>
<lease/>
</host>
</dhcp>
