This should de-flake the codeintel-qa tests by ensuring that for an upload to be successful we wait until the commit graph is updated. This should mean that any failures during query should point to a problem in the backend, not in the timing between the test phases.
An overview of the flow:
start a goroutine to upload each index file
wait until we get an id back for each upload, and submit those ids to a watcher
the watcher will continually poll the API for the upload status
(new) once an upload is processed, we begin to query the repository commit graph status
block on each repo until the indexes are finished processing in the background
(new) block on each repo until the commit graph has been refreshed after all uploads have been processed
