[TASK] Deprecate second controller action argument

Core eid and backend dispatching uses only the $request object as
argument, but not the prepared $response object anymore. This was
a misconception in the first place.

The patch deprecates the second argument and logs deprecations
by reflecting the target action at runtime. This can be supressed
with a new feature toggle.
