Fixing bugs in strategies

Browse source 
* Don't filter hosts remaining based on their failed state. Instead rely
  on the PlayIterator to return None/ITERATING_COMPLETE when the host is
  failed.
* In the free strategy, make sure we wait outside the host loop for all
  pending results to be processed.
* Use the internal _set_failed_state() instead of manually setting things
  when a failed child state is hit
