* provider/aws: Re-implement api gateway parameter handling
this PR cleans up some left overs from PR #4295, namely the parameter handling.
now that GH-2143 is finally closed this PR does away with the ugly
`request_parameters_in_json` and `response_parameters_in_json` hack.
* Add deprecation message and conflictsWith settings
following @radeksimko s advice, keeping the old code around with a deprecation
warning.
this should be cleaned up in a few releases
* provider/aws: fix missing append operation
* provider/aws: mark old parameters clearly as deprecated
* provider/aws work around #8104
following @radeksimko s lead
* provider/aws fix cnp error
Change the `RetryFunc` from a plain `error` return type to a
specialized `RetryError` which must decide whether it is
retryable or not.
Add `RetryableError` / `NonRetryableError` factory functions that
callers are meant to use to build up these errors.
This makes it eminently clear whether or not a given error is
retryable from inside the client code.
Goal here is to _not_ change any behavior, simply reflect the
existing behavior with the new, clearer, API.
