* feat: Retry behavior

* Introduce `retryable` property to auth library exceptions. This can be
  used to determine if an exception should be retried.
* Introduce `should_retry` parameter to token endpoints. If set to `False`
  the auth library will not retry failed requests. If set to `True` the
  auth library will retry failed requests. The default value is `True`
  to maintain existing behavior.
* Expanded list of HTTP Status codes that will be retried.
* Modified retry behavior to use exponential backoff.
* Increased default retry attempts from 2 to 3.
