/**
* An internal strategy to fail fast any request that goes through it.
*
* This class is considered internal! For external purposes we recommend extending the {@link BestEffortRetryStrategy}
* and only failing on certain {@link RetryReason} as needed or based on a request context or external property. Using
* this strategy here directly, if not used carefully, will lead to lot of copy/pasting of try/catch blocks and not
* to clean code.
