Pull #171

travis-ci

Add `warn_on_re_ask` OptPro kwarg

- Dictates whether a warning should be printed when internal
  optimizer suggests a point that has already been evaluated
- Moves logic for replacing duplicate suggestion with a random
  point from `protocol_core.SKOptPro._get_current_hyperparameters`
  to `backends.skopt.engine.Optimizer._ask`
   - This happens immediately after logging the warning (if necessary)
