dnsmasq can match tags in its dhcp-range configuration, this commit adds
the option to configure it in the dhcp section

uci configuration:
config dhcp 'lan'
        option interface 'lan'
        list tag 'blue'
        list tag '!red'
        option start '10'
        option limit '150'
        option leasetime '12h'

generated dnsmasq configuration:
dhcp-range=tag:blue,tag:!red,set:lan,192.168.1.10,192.168.1.159,255.255.255.0,12h
