com.hazelcast.multimap.impl.client.KeyBasedContainsRequest
The KeyBasedContainsRequest can be used to determine if a key is available in a multimap (when value is null), or to check if a map-entry is stored in the multimap (value not null).
This request is 'cheap' since it will always be routed to a particular member in the cluster, unlike the {@link ContainsRequest}.

        mm.put("key2", "value2");
        mm.put("key3", "value3");


        //contains key value
        final SimpleClient client = getClient();
        client.send(new KeyBasedContainsRequest(name, ss.toData("key1"), ss.toData("value1")));
        boolean result = (Boolean) client.receive();
        assertTrue(result);


        //not contains key value
        client.send(new KeyBasedContainsRequest(name, ss.toData("key1"), ss.toData("value2")));
        result = (Boolean) client.receive();
        assertFalse(result);


        //contains key
        client.send(new KeyBasedContainsRequest(name, ss.toData("key2"), null));
        result = (Boolean) client.receive();
        assertTrue(result);


        //not contains key
        client.send(new KeyBasedContainsRequest(name, ss.toData("key4"), null));
        result = (Boolean) client.receive();
        assertFalse(result);


        //contains value
        client.send(new ContainsRequest(name, ss.toData("value3")));
