Add FastAPI migration of licenses endpoints

[davelopez]

Related to #10889
I decided to migrate the easiest API endpoints I found as a FastAPI exercise (and to break the ice) :)

Some comments:

• I decided to add a couple of type annotated methods to the LicensesManager instead of using the existing ones so I can slightly change their behaviour while maintaining the previous controller intact.
• I assumed that the /api/licenses/{id} endpoint will always be invoked using an SPDX identifier as Path parameter and not an url (the manager supports both). If the URL must be supported the Path parameter should be changed to a Query.

TODO:

• Add functional tests for the licenses API endpoints

That's looking very nice!

This code hasn't been included in a Galaxy release yet - this is probably the best time to get everything perfect and synchronized. For instance, I would move that if license is None: raise ObjectNotFound() right into the manager.

Thanks for the quick review!

I tried to fully document the API endpoints to serve as an example.
Also, I took the liberty to add documentation for the API tags here as explained in the FastAPI documentation.

Did I break the RolesApiTestCase::test_create_only_admin test somehow? 😳

I've seen this fail before in other PRs, just one of those flaky tests we'll try fixing on Monday.

Thanks for resolving the conflict! :)
