Triage notes

Triage notes 2016-06-24:

• label hygiene:
  • deleted unused labels
  • add puppet4 label to tickets with puppet4 implications
  • add backwards incompatible label to cluster breaking changes
  • add needs rebase label, agreed we'd rebase trivial changes ourselves
• PR sweep (prioritizing puppet 4 related changes)
  • return to 468 - needs a more complicated functional review
  • return to 465 - might have weird implications because it turns on a previously
• TODOs
  • update gh-pages branch with changelog and changes from this triage and the 2.0.0 release.
