Although, I don't want to stuff every option for things like this into
NM.  Since obsoleting dhcdbd, what I'd like to see is this:

a) NM exports a D-Bus interface (the most likely object for this is the
Connection that just got activated) that allows things to query the DHCP
information.  This interface sends out signals when the DHCP information
is cleared/updated/etc

b) NetworkManagerDispatcher listens for these signals and executes
scripts to do things with them, or something like that.

I think it makes sense for static routes and such things to be handled
by NM, but we quickly start getting to things that I don't think
_should_ be handled by NM itself.
