tools/dnsmasq-leases-html: create a HTML page with leases from dnsmasq

Parse the file that contains all the leases assigned by dnsmasq, and
create a static HTML page from it. This can be served by nginx to make
it easy to see what IP is assigned to a machine, and which machines are
currently on the network.
