_retryCount is shared between multiple requests making it dangerous to infinite requests

[itsUndefined]

Describe the bug Because _retryCount is not local var to _attemptRequest, it's possible to create infinite loops since a new request restarts the _retryCount to 0 for all pending requests.

To Reproduce

1. Add a shouldAttemptRetryOnResponse that starts a new request with the same intercepted client that succeeds ( e.g. a refresh )
2. Make an api request that fails all the time and calls shouldAttemptRetryOnResponse
3. Observe infinite looping

Expected behavior I expected that after maxRetryAttempts attempts of the original request, the request would be cancelled
