Feature #40907: mgr/dashboard: REST API improvements
mgr/dashboard: Automatic generation of REST API documentation based on Python docstrings
In the current implementation of the Ceph-Dashboard we already generate a Swagger-UI page with the available REST API endpoints that are implemented in the dashboard backend. This generation is automatic and it's done when the dashboard module starts.
The REST API endpoints correspond to Python class methods decorated with `@Endpoint`, and, in the special case of the REST controllers, correspond to the following class methods: `list`, `create`, `get`, `set`, `delete`, `bulk_set`, `bulk_delete`.
The objective of this feature is to parse the docstrings of the endpoint methods and add these to the Swagger-UI page to document each endpoint.
We could also agree on a particular python docstring format to allow the specification of the parameters types and return types and add also add that information to the Swagger-UI page.

There is no suitable off-the-shelf parser that can be used to accomplish this.
Another way to obtain information for the documentation directly from the code is to use annotations and decorators. This approach will be used instead.
However, function annotations can not be used since it is not compatible with Python2.
It is desirable but not mandatory that the solution includes responses.
