Prep backend-explicit-tests for merge

[mattsb42-aws]

Given the relative number of changes, I figured it would be better to merge master into backend-explicit-tests first before merging backend-explicit-tests into master. That way the changes are smaller and more reviewable.

Next step from here will simply be merging backend-explicit-tests into master.
