When Kodiak starts merging a PR, it enters a loop, polling until the PR is ready to merge. If Kodiak makes a GitHub API request and encounters an error, it will eject from this loop, ignoring the PR and moving on to the next PR in queue.

We should audit all of our API requests to ensure we gracefully handle errors.
