It turns out that Cassandra does not allow IN restrictions together with
filtering, except, curiously, when the restriction is on a clustering key.
There is no real reason for this limitation - the error message even says
it is not *yet* supported.
Scylla, on the other hand, does support this case. Of course it's not
enough that we support it - we need to support it correctly... But we don't
have a full regression test that this support is correct - in
filtering_test.cc we test it with clustering and regular columns - but not
partition key columns.
So this patch adds a simple cql-pytest test that this sort of filtering
works in Scylla correctly for partition, clustering and regular columns
(and also confirms that these cases don't work, yet, on Cassandra).
