allow input path override (#1536)

Summary:
Pull Request resolved: #1536

## What is this stack

- Bolt has been used in canary for weeks now and we haven't seen reports of any issues
- It's time to productionize
- Early in the stack, I rework some logic to raise the quality bar a bit. At the end of the stack, I delete the legacy runner.

## What

- When resuming a run, update the input path on the instance

## Why

- This makes it so that advertisers who fail during input data validation can update their input file and continue the run (instead of having to wait for the instance to expire)
