Possibility of disabling raw socket use in Kea ?

Hi,

The code in Kea is prepared to switch between the use of raw sockets and
regular datagram sockets. But, currently the selection is hardcoded and
there is no configuration parameter to control this selection by the
administrator. We're now going through some refactoring of the
configuration code, so once this is done we can easily implement the switch.
