Add API endpoint to get frozen jobs

This allows a developer to query what the jobs will look like for a
project against a pipeline for a branch tip. It will return the list of
jobs and their dependencies that will be used in the pipeline buildset.

The idea is that this will be consumable as a way of reconstructing jobs
locally for debugging.
