Aggregate pacts with duplicate interactions into a single "uber pact" to reduce verification time

[canny]

When a new version of a pact is published, it generally has a lot of overlap with the previous pact content. The amount of time that the verification takes could be greatly reduced by returning a single "uber pact" that had a unique copy of each interaction, and then fanning out the verification results back into each individual pact on results publication.

(we've since deprecated the canny roadmap, and tracking work via GitHub. The source ticket has more info in, so worth keeping that, and disregarding this)
