Also mention the bug in the commit message, just link it like

https://bugzilla.redhat.com/show_bug.cgi?id=913446

Needs documentation but that will be dependent on what the final patch looks
like, so fine to skip for now.

The main questions are:

1) is the XML format fine? <range ... lease='XXX'/>. lease sounds kinda
non-specific to me, maybe leasetime or leaseTime.

2) what to use for the input format? right now it's just string passthrough to
dnsmasq, which takes a format like XX[s|m|h|d|w], or 'infinite'. Accepting
that format kind of sticks us with that for all time, which probably isn't a
good precedent. the easy way would probably be to just say the value needs to
be in minutes, and maybe -1 == infinite. But that will take a bit more code to
adapt that value to the dnsmasq format.
