`validate_options` needs to be extended with `topology` parameter, because NetworkTopologyStrategy needs to validate if every explicitly listed DC is really existing. I did cut corner a bit and trimmed the message thrown when it's not the case, just to avoid passing and extra parameter (ks name) to the `validate_options` function, as I find the longer message to be a bit redundant (the driver will receive info which KS modification failed). The tests that have been commented out in the previous commit have been restored.
