With this change, the Controller is now aware of its own listeners in a
more codified and structured way.
The reasoning behind these changes are as follows:
1. Currently, we're iterating over these listeners in multiple spots
along this initialization flow to check each listeners' purpose. By
doing this once when we create a Controller and essentially storing the
result, we can clean up the downstream code to use those results.
2. Initial effort to centralize Controller validation. At the moment, we
are doing a lot of validation all over the `cmd` and `config` packages.
From a conceptual perspective, Controller-related validation should
be performed in the function that is responsible for constructing the
Controller object itself. This enables any developer to look in a
single place for all the constraints that we place on creating a
Controller.
Don't rely on token for scopes collection actions
This requires `scope_id` to be passed (via query param) for actions on
the scopes collection; that is, listing or creating. However, it removes
the dependency on using the token for the scope of the command. For
actions on a specific scope, we use the given ID to determine the scope
we should be operating at, doing a lookup if necessary.
Existing tests have been updated. Of particular note, the CORS test was
already operating on the scopes collection so served as a good test to
ensure that from an API level the scope_id parameter was being parsed
and passed through (the tests fail without adding that query parameter
in).
