Review Comment:
   I updated the implementation by adding `GetHost()` to `ExecutableQuery`.
   
   Also, I looked over my implementation and found a bug leading to endless 
query execution... It appears when the host passed to `SetHost()` is not UP. I 
changed the behavior 
[here](https://github.com/worryg0d/gocql/blob/c1e46be251fc5779a2cb6a8a52cee03a8a161275/query_executor.go#L148)
 not to pick the next `selectedHost` when the selected one is not up and 
`GetHost()` returned no host.
