* feat: add more authentication information to swagger
* updates the `docs-settings` to make the generated swagger
`securityDefinitions` include both JWT and CSRF methods, as well as
basic. A few linter fixes happened as a side effect.
* Put in wordier descriptions for all three, since we don't have great
shared documentation about authn/authz.
* Added CSRF to `login_session`, which also serves as a proof of concept
for other endpoits
* Also regenerated the swagger doc, which picked up some extra changes.
Generated swagger now has help and allows extra auth methods so some
preveiously unusable endpoints can be hit.
FIXES: APER-3554
This adds the ability to get a list of detailed courses based on their
keys provided in the newly added `keys` query param in the `GET /courses/v1/courses/`
endpoint.
* Swagger was renamed to OpenAPI at some point so use the new name for
clarity.
* Prefix with `lms` to make it clear that these are the APIs from the
LMS and may not all be available in the CMS.
