dhcp: T2265: refactor DHCP class

Break the code between v4 and v6, remove need for getter/setter
as they are just exposing the underlying dict.

Move FixedDict from tunnel code and expose it to other part so
it can be used to prevent accidental change to the dhcp option if
no default exists already.
