Brian Buchalter 6be9c498bc Provide context when logging unpermitted parameters
Currently, the payload of the unpermitted_parameters.action_controller
events emitted by StrongParameters does not provide enough information for
developers to understand which controller and action received the
unpermitted parameters. This PR modifies ActionController::Parameters to
allow callers to specify a "context" which is included in the logging
payload.

*Implementation Strategy*
Since the ActionController::Parameters class is only loosely coupled
with controllers and can technically be used in any context, this PR
expects the caller to provide logging context.

Since StrongParameters is caller in Rails and has access to the
request object I chose to provide a payload similar to the
start_processing.action_controller event.

= Action Pack -- From request to response

Action Pack is a framework for handling and responding to web requests. It
provides mechanisms for *routing* (mapping request URLs to actions), defining
*controllers* that implement actions, and generating responses by rendering
*views*, which are templates of various formats. In short, Action Pack
provides the view and controller layers in the MVC paradigm.

It consists of several modules:

* Action Dispatch, which parses information about the web request, handles
  routing as defined by the user, and does advanced processing related to HTTP
  such as MIME-type negotiation, decoding parameters in POST, PATCH, or PUT bodies,
  handling HTTP caching logic, cookies and sessions.

* Action Controller, which provides a base controller class that can be
  subclassed to implement filters and actions to handle requests. The result
  of an action is typically content generated from views.

With the Ruby on Rails framework, users only directly interface with the
Action Controller module. Necessary Action Dispatch functionality is activated
by default and Action View rendering is implicitly triggered by Action
Controller. However, these modules are designed to function on their own and
can be used outside of Rails.

You can read more about Action Pack in the {Action Controller Overview}[https://guides.rubyonrails.org/action_controller_overview.html] guide.
