ftpfilez_backoff (ftpfilez v2.3.0)

Short-lived cache for connection/login failures.

This prevents a queue with many jobs for the same FTP credentials from opening many connections that are very likely to fail with the same error. Only connection setup errors are cached; file operation errors are not.
