Cluster instantiation fails if any contact points' hostname resolution fails
Description
Per some discussion in this ML thread, the driver has some unintentional behavior on Cluster instantiation when a contact point does not resolve. Currently this raises an exception. Instead, it should warn on each that fails, but continue to try to resolve the other contact points.
