[Kea-users] Ignore non-reserved hosts

[Francis Dupont]

There are in recent Kea versions KNOWN and UNKNOWN classes and I merged
in the development Kea version a change in the DROP class to allow to make
it to depend on KNOWN or UNKNOWN (it adds another way to ignore non
reserved hosts with guards to subnets and/or pools with a different
behavior as queries are dropped vs. no resource can be assigned).

PS: Change 1898 included in Kea 1.9.8.
