Triage labels for WIP tests

Triage Labels

PR #131 introduced about 1200 test cases marked @wip. These need some kind of triage process to help prioritize and address the work.

Triage in general requires at least 3 categories: won't-fix, must-fix-now, and will-fix-later.

Things related to protobuf, I feel can be lumped into won't-fix. It's not as widely used in the Python world. I think it's a distraction from the underlying purposes of extending C7N to include easier-to-read logic expressions and computations.

The must-fix-now and will-fix-later tags have a more subtle distinction. I think I could be driven by (a) how clear the affected code is and (b) how soon someone can get to the change. It may be clear but you can't get to it right away. In that case, an issue can have detailed notes that stage something as will-fix-later. The will-fix-now are ones where the change is clear and (perhaps) already tested in a branch.

So. Question 1 is "What labels should we use?"

PR #174 will add even more test cases marked @wip.
