Subject: [PATCH] rclone-backup: throttle API calls to survive Drive rate
 limits

The nightly sync has failed since Jul 18 with RATE_LIMIT_EXCEEDED,
transferring 0 B. Limit transactions and pace Drive requests, and retry
a few times before giving up. This mitigates rather than fixes the cause
(the remote still uses rclone's shared default client_id).
