dnsmasq: Add match section support
Match sections allow to set a tag specified by the option networkid if the client
sends an option and optionally the option value specified by the match option.
The force option will convert the dhcp-option to force-dhcp-option if set to 1 in
the dnsmasq config if options are specified in the dhcp_option option.
