Allow migrating up and down

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
