Custom DHCP options
Sometimes, users need to pass custom options to client via dhcp.
A common option is a custom DNS server, but we might include every possible option. Maybe DNS could go to the panel (different DNS for every zone/interface) and other options to the db with a setprop.

I lost the formal verification output of all test cases, but everything was correct.
I have installed the update on a production system, changed some values and obtained a new lease.
In particular, I changed lease time from 1 to 2 days and here are the logs:
Lease time 1 day:
Aug 5 15:21:21 ns65 dhclient1156: bound to 192.168.5.55 -- renewal in 33860 seconds.
Lease time 2 days:
Aug 6 00:36:09 ns65 dhclient29753: bound to 192.168.5.55 -- renewal in 68992 seconds.
