Auth0 auth backend: Infer CRUD operation from decorated function name

[chmreid]

For the Auth0 backend, the security decorator needs a method keyword to be specified. This requires manually updating all decorators, by hand, when swapping out the Auth0 backend.

To reduce (not completely eliminate) this work, we could infer the CRUD method from the function name:

• put -> create
• get -> read
• patch -> update
• delete -> delete

Not all the decorated function names fit this convention (e.g., list_collections) though
