Markus Schirp 40c337ce5b Fine grained rspec integration
* Flattens the rspec example groups on filtering to remove redundant
  work being done on executing subtrees of already executed example
  groups
* Uses test batching to kill one mutation per isolation that results in
  a significant speedup.
* Drop rspec 2 support.
