* Added a failing test for the multi-oauth-router issue
* Fixed the #823 regression.
Using a regex for the backend name validation instead of an enum.
* Fixed formatting errors
* Moved the `AuthenticationBackendName` enum to `Authenticator`
This prevents an issue with OpenAPI schema generation caused by two
endpoints accepting a parameter with a duplicate name.
* Applied `make format`
* Added format-check to makefile
* Added a "Check codestyle" step to the build action.
* Rerun `make format`
* Added a "lint" target to makefile
* Added lint step to the build action
* Added W503 to the list of ignored flake8 errors.
See https://www.flake8rules.com/rules/W503.html
* Added OAuth2 authorize route response_model
* Changed OAuth2 "authorize" route backend param type.
On OAuth2 router creation, an enum is created for the `authentication_backend` parameter. This allows us to generate OpenAPI docs correctly.
* Reformatted with "make format"
* Updated OAuth2 authorize url docs
- /authorize now returns 422 instead of 400 for an invalid authentication backend
* Names for urls added
* Tests for Login/Logout Names
* Register Name Test
* tests/test_router_reset.py
* Tests to verify url names in users router
* Test Verify Router Names
* oauth routes updated with prefix
* Test for authorize. Didn't right test for callback as covered under other tests
* Replace unused `for` index with underscore
* Use `items()` to directly unpack dictionary values
* Merge duplicate blocks in conditional
* Use `any()` instead of for loop
* Format __init__.py
* Remove database adapter in favor of external dependencies
* Prevent flit from installing all optional dependencies when testing build
* Remove MongoDB service during CI build
