[BUG]: Requests are always passed through when clients wait based on Retry-Header value returned #241
Description
This bug affects both the GenericRandomErrorPlugin and GraphRandomErrorPlugin when simulating throttling.
If the first request is throttled and the app waits for the Retry-After period before sending the next request, the request is always passed through.
The proxy should either pass through the request or fail the request with a random error based on the configured failure rate.
