Because polyculeconnect is a OIDC proxy, we need to know which auth backend to use. This is provided using a query param or a form, so we need to get it from our own middleware. This commit adds the following elements: - basic DB storage for the backends - support for DB migrations and a first test migration (not definitive) - middleware to get the backend from the request and put it in the context - test that the backend exists in the auth flow
