This PR changes the TypeSafeMiddleware handlers so that the TypeSafeMiddleware is initialized before, Query parameters, Identifiers and Codable objects.

Motivation and Context

This change was requested for two reasons:

  • So that you can have a TypeSafeMiddleware that logs Query parameters even when the query fails to be decoded
  • So that you can have a TypeSafeMiddleware that altered the request before it is decoded into a Codable object (E.g. Changing the request decoder that will be used)

How Has This Been Tested?

The existing TypeSafeMiddleware tests have been run and are all still passing.

@Andrew-Lees11 can you add tests for the two example cases you mentioned in your opening comment?

I have added a test case for logging the query parameters using a typeSafeMiddleware even if they are incorrect. This would have failed before but is now possible since the middleware is run before the query is decoded. With changing decoder, since we are no longer making them public this is no longer a use case.
