Adding facts module

Hi,

At our site we found interesting to have a facts module providing information about network interfaces configuration available via DHCP. This can be used to write a static configuration basing on current DHCP (we use fixed address in DHCP configuration) or to compare current resolvers, netmask and so on with the one delivered via DHCP.

I’d like to share this work, but I’m not sure if should I try to go with it to setup module, or extra modules?
The initial version of sources is available here https://github.com/cinek810/misc/blob/master/ansible-modules/dhcp_netconfig

of course I’ll add some documentation before eventual pull request, but do you think it’s interesting ? If so what are your suggestions about next steps?

cheers,
marcin
