Allow filtering on the students metrics endpoint

For:

• https://github.com/hypothesis/lms/issues/6418

Testing

• Check the all courses dashboard page
• Check the course assignments page
• Check the assignments students page. This is broken now until the FE starts passing assigment_id as a query parameter.

@acelaya Keeping this as draft.

If we went for something like this we'd need the FE to start sending assigment_id as a query parameter instead of as part of the URL template. We can sync about how to merge/deploy the changes together.

I'll create a PR based on this one, updating the FE

I have tested the "new" endpoint and it throws a 404. Could we be missing some of those empty __init__.py files somewhere?

This "works", it's not a 404, :thinking:, taking a look

@acelaya It was a classic assigment vs assignment. I going to write a git hook to catch these. Should work now.
