    Enable adding new tag with options

    It is useful to add a new tag when update the options
    with dnsmasq.
    We have a use case in Ironic to support ipxe with dnsmasq.
    It looks like this:
    dhcp_opts.append({'opt_name': 'tag:!ipxe,bootfile-name',
                      'opt_value': CONF.pxe.pxe_bootfile_name})
