Custom exception factory for deserialization exceptions

[ted-ccm]

Is your feature request related to a problem? Please describe.

Currently there is no way to suppress refit exception from including request parameters like headers and query string which could include sensitive information that needs to be prevented from being dumped into the log.

Describe the solution you'd like

Add an additional property in RefitSettings.cs similar to ExceptionFactory that allows overriding refit's default exception during deserialization exception.

Describe alternatives you've considered

Wrapping all requests with try and catch and throwing custom exception works but it is a bit clunky and risky as it there is a possibility that someone might rethrow the exception or forget to wrap the request in try and catch completely.

Describe suggestions on how to achieve the feature

Add a property in RefitSettings.cs...
public Func<HttpResponseMessage, Exception, Task<Exception?>>? DeserializationExceptionFactory { get; set; }

Use the factory in RequestBuilderImplementation.cs in BuildCancellableTaskFuncForMethod

Override both deserialization exceptions...

...
catch (Exception ex)
{
    //if an error occured while attempting to deserialize return the wrapped ApiException
    if (settings.DeserializationExceptionFactory != null)
        e = await settings.DeserializationExceptionFactory(resp, ex).ConfigureAwait(false);
    else
    {
        e = await ApiException.Create(
            "An error occured deserializing the response.",
            resp.RequestMessage!,
            resp.RequestMessage!.Method,
            resp,
            settings,
            ex
        );
    }
}
...

...
catch (Exception ex)
{
    if (settings.DeserializationExceptionFactory != null)
        throw await settings.DeserializationExceptionFactory(resp, ex).ConfigureAwait(false);
    else
    {
        throw await ApiException.Create(
            "An error occured deserializing the response.",
            resp.RequestMessage!,
            resp.RequestMessage!.Method,
            resp,
            settings,
            ex
        );
    }
}
...
