Proposal: Create API endpoint to derive runs for a `job_version`

[phixMe]

In the current specification of the API, there is no way to derive the runs for a particular job version.

The API to list a particular version of a job defined as `/api/v1/namespaces/{namespace}/jobs/{job}/versions/{version} returns only the latest run for the job version. It is very likely users will want to be able to see all the runs instead of just the most recent one.

New Endpoint:

/api/v1/namespaces/{namespace}/jobs/{job}/versions/{version}/runs

Query Params

limit: The number of results to return from the offset
offset: The initial position from which to return results

Response

{
   runs: RunSchema[]
}

Note: Namespace and Job aren't really required since we have the job_version UUID, but we wish to follow the conventions of our existing specification.

To retrieve a run, we expose the endpoint /jobs/runs/{id} since we don't need the namespace or job and run IDs are globally unique. We can also do the same to return the N runs for a given job version as they are also globally unique:

GET /jobs/versions/{id}/runs

That said, we currently do expose the following API to retrieve a job version:

GET /api/v1/namespaces/{namespace}/jobs/{job}/versions/{version}

So, we may want to be consistent, as you mentioned, or support both cases.
