    dnsmasq: add dhcp-range tags configuration
    
    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
