Review Comment:
   How about adding a private interface like:
   
   ```
   type cqlQuery interface {
       ExecutableQuery
       getHost() *HostInfo
   }
   ```
   
   And make gocql internal code use `cqlQuery` (name subject to change?) 
instead of `ExecutableQuery` so that we don't have to worry about breaking the 
public `ExecutableQuery` interface when we add new functions to `Query` or 
`Batch`?
