Update manifest service

[dpgraham4401]

Description

This is a relatively large PR. It adds the following to our project.

1. a update_manifest internal service. It currently just updates the manifest in our system. There is not an exposed view/handler.
2. Updates our model manager custom .save() method. We use our internal save method to abstract away the create/update process. It builds on existing Django ORM functionality.
3. Refactor the logic of MtnListView handler/view into a service module function that allows us to filter all manifest by epa_id and site_type (for example, the get_manifest service could return all manifests that the user has access to a site that is listed as a generator). I'm happy with the way this turned out, it follows the django-styleguide approach of placing business logic into our service modules.
4. MtnTable filtering now stores status/search state in URL search parameters so the link can be (1) revisited and (2) shared.
5. miscelaneous other things like
   • replace yield with return where appropriate in our factories as fixtures.
   • update a few minor dependencies.
   • rename serializer/views to be internally consistent
