Add netconf module
Debian libnetconf2 package only ships a shared .so library so ultimately we need some other way to pull that in as a static lib. We can leave it as is for initial step though. It should only become run time dependency for programs importing the netconf module.
I'm leaning towards not using libnetconf2 since it seems like we are loosing quite a bit of control in the low level socketry. The netconf part should be fairly minimal anyway, my main motivation for using libnetconf2 in the first place is to get something that decodes the netconf payload using a yang schema, but seeing how that is mostly libyang, we can get that functionality anyway by pulling in libyang.
Closing, there is now a native netconf client https://github.com/orchestron-orchestrator/netconf - or at least an embryo of one, it does the basics.
