DHCP ISC Smart Proxy Plugin / Static reservations

Hi there… I created a DHCP ISC Smart Proxy Plugin(an extension), which
handles special cases, like ability to have static reservations in
dhcp.conf and not raise exceptions by creating/deleting records for such
This is sometimes needed… if you need to have a few hosts at the network
not to be under Foreman-Proxy control. Having really static reservations…
Especial if you remove a host from Foreman, it should stay in dhcp with
MAC-IP reserved.

here is the projects:

I am rather new to Foreman/Ruby… so I did it on my best :)) It would be
great if somebody with experience could look at it.
